Patch 2.1.66 on the Advanced Server is a systems patch disguised as a hero patch. The headline is obvious, Hirara arrives, but the more important part is how many older names received tempo, survivability, or scaling corrections at the same time.
Using MLBBHub's March 20 patch reference as the primary source, this update pushes assassins, smooths several failed revamps, and continues Moonton's seasonal habit of fixing one problem by creating two cleaner ones. That is still progress.
#Patch 2.1.66 at a glance
The fastest way to read this patch is by role impact, not by raw changelog order. New hero releases distort bans and test rates, while revamps distort perception. The numbers below track likely ladder pressure, not promotional text.
| Patch area | Change volume | Likely ranked impact | Verdict |
|---|---|---|---|
| New hero | 1 major release | Very high in bans, medium in actual stable win rate | Immediate draft tax |
| Hero buffs | 4 to 6 meaningful adjustments | High for mid and gold lane | Real meta movement |
| Hero nerfs | Limited direct removals | Low short-term suppression | Soft correction, not gutting |
| Revamp tuning | Multiple follow-up edits | High uncertainty for 1 week | Typical Advanced Server cleanup |
| Battlefield or system edits | Present but secondary | Medium | Supportive, not defining |
The important distinction is this: 2.1.66 does not reset the meta by itself. It accelerates trends already visible after MLBB Patch 2.1.64 Advanced Server: Three Clear Meta Winners, especially burst access, cleaner lane priority, and lower patience for clunky kits.
#Hirara enters as the patch's central variable
1 new hero, 0 stable matchup samples, 100% guaranteed discourse inflation. That is how Advanced Server releases work.
Based on the patch reference, Hirara is the largest immediate draft variable because new assassins always overperform in perceived threat before they overperform in win rate. Mobility, target access, and unfamiliar damage windows force bans even when the numbers are not yet solved. Ranked players hate uncertainty more than damage.
| Hero | Role profile | Immediate pressure | Why it matters |
|---|---|---|---|
| Hirara | Assassin, burst access | Very high | New mechanics create forced respect in draft |
| Existing backline mages | Squishy scaling cores | Negative | Less room to position greedily |
| Immobile marksmen | Late-game DPS | Negative | More punish windows in side lanes |
| Peel supports | Utility backline cover | Positive | Draft value rises when new dive threats appear |
The practical effect is simple. Even before stable server data exists, Hirara raises the value of anti-dive structure in drafts. Moonton keeps introducing mobility problems, then sells discipline as the answer. Efficient, if repetitive.
#Revamp and follow-up buffs point to failed first drafts
Multiple heroes in 2.1.66 receive adjustment packages that read like corrections to earlier undercooked tests. When a patch revisits several names at once, that usually means the first numbers missed lane thresholds, clear speed thresholds, or survivability breakpoints.
| Hero group | Type of change | Meta signal | My read |
|---|---|---|---|
| Revamped heroes | Smoothing, usability, or damage tuning | Previous version underdelivered | Moonton is salvaging adoption |
| Gold lane carries | Direct buffs or lane-friendly tuning | Side lane damage race intensifies | Gold lane priority rises |
| Tempo mages or hybrid threats | Better uptime or cleaner execution | Mid priority shifts toward faster rotation | Roam timing gets tighter |
This matters more than the raw patch text. Follow-up tuning after a revamp is usually the real version of the hero. The first release tests the concept, the second patch admits what the concept failed to do in lane.
#Gold lane gets another nudge upward
Several patch references around 2.1.66 point to buffs for names like Wanwan, Brody, and Harith in community summaries tied to this update cycle. Even without treating third-party summaries as primary evidence, the pattern lines up with the patch's broader direction: more reliable lane pressure, earlier payoff, less punishment for aggressive spacing.
| Gold lane trend | Before 2.1.66 | After 2.1.66 direction | Impact |
|---|---|---|---|
| Early kill threat | Moderate | Higher | Roam visits become more decisive |
| Safe scaling | Already strong | Still strong | Weak laners lose room to recover |
| Draft flexibility | Narrower around comfort picks | Expands if buffs stick | Ban pressure spreads |
| Backline safety | Manageable with standard peel | Worse against new dive tools | Front-to-back drafts lose margin |
If these changes reach live close to current values, gold lane becomes less forgiving. Not harder in a noble strategic sense, just less tolerant of weak trading patterns.
#Mid lane and utility value rise through indirect pressure
The patch's direct hero notes are only half the story. New dive threats and side-lane buffs increase the value of mids who clear fast, move first, and punish overextension before assassins arrive.
That does not automatically create a mage patch. It creates a priority patch for tempo. The mid heroes that survive are the ones that either leave lane faster or force too much space control to be ignored.
| Mid lane attribute | Value before patch | Value after 2.1.66 | Reason |
|---|---|---|---|
| Wave clear speed | High | Very high | Side lanes need earlier coverage |
| Self-peel | Medium | High | New dive pressure increases punishment |
| Burst confirmation | High | High | Shorter fights favor reliable damage |
| Long setup poke | Medium | Lower | Slower win conditions lose time |
Readers looking for a clean forecast should keep it simple. This patch favors tempo mids, reliable peel, and side lanes that can convert early assistance. Slower scaling drafts lose draft equity the moment Hirara is hover-banned into every lobby.
#Winners and losers from patch 2.1.66
A patch this broad creates relative winners even before exact ladder data settles. The point is not perfection. The point is identifying which class gains more decision-making power from the new environment.
| Group | Status | Data-backed reason |
|---|---|---|
| Assassins | Winner | New hero release and increased backline pressure raise class priority |
| Peel supports | Winner | Anti-dive utility gains value immediately |
| Tempo mages | Winner | Faster lane exits matter more than raw late scaling |
| Immobile marksmen | Loser | More access points, less room for error |
| Slow revamps still needing help | Loser | Follow-up patching signals unresolved design problems |
| Front-to-back only drafts | Loser | Less stable when side lane volatility rises |
The biggest winner is draft pressure itself. Teams do not just need stronger heroes, they need fewer weak points. 2.1.66 increases the tax on any lineup that cannot protect its backline without sacrificing map tempo.
#What this patch means compared to 2.1.64
Compared to MLBB Patch 2.1.64 Advanced Server: Major Shifts, patch 2.1.66 is less about declaring new power centers and more about tightening them. The earlier patch exposed which classes were getting ahead. This one sharpens the edges.
| Patch | Main theme | Effect on meta |
|---|---|---|
| 2.1.64 | Broad reshaping, early winners emerge | Opened space for several role shifts |
| 2.1.66 | Correction plus acceleration | Pushes faster drafts and stronger punish windows |
That is why 2.1.66 matters. It is not flashy because every line is broken. It matters because it reduces the margin for weak drafting and clumsy lane phases. Advanced Server patches often look harmless right before they become annoying on live.
#Final verdict on MLBB Advanced Server patch 2.1.66
Patch 2.1.66 is favorable for proactive comps and unfavorable for passive scaling. Hirara is the visible headline, but the more durable effect is the patch's support for cleaner lane pressure, faster rotations, and harsher punishment on static backlines.
If Moonton ships most of these values unchanged, the next stable environment gets faster, sharper, and less forgiving. That usually means better viewing, worse solo queue, and another week of players pretending their draft had enough peel.
