Honestly, instead of constantly shifting BRs around, maybe fix the real issue with the game: compression. Just reduce the BR gap from 1.0 to something like 0.7 — that alone would solve half the problems.
As someone who used the T-55AM, I always found it hilarious when people said it was ‘broken’ at 7.7. Of course it was OP, like any tank does when it’s fighting enemies a full BR below. Same logic applies when I use a Tiger II and see things like the PzH 2000, Conquerors, M103s, etc and getting shot by HEATS, that feels disgusting.
People forget how mid the T-55AM really is: terrible dart, sluggish as hell, trash reload speed, bad reverse and awful turret traverse. Meanwhile, the AMD is straight-up better at that BR because APS is insanely overpowered, it hard-counters ATGMs from helis and ground, a real life saver, not like that extra armor that people rarely hit, most hits are near gun that doesnt have protection. The T-55AM suffers from the usual issue: is overpowered at low tiers were shit dart good enouth(aphe even better there) and armor works for real, then becomes garbage at high tier. That dart? Its a 8.3 dart at most(the dart itself, not tank that was good at 8.7) and armor useless.
The T-55AM was my first pick at that BR mainly because of the premium bonuses and the fact that it was solid enough at that tier. That meant I usually got better stats than with the AMD, simply because I had more good games where I survived longer and racked up kills. But in reality, the AMD is the better vehicle, just not enough better to justify giving up the premium rewards. Now It’s a subpar premium completely outclassed. You’ve got the T-62M with similar armor (but a way better turret), slightly slower mobility, and that 115mm 3BM28,an absolute monster that punches through anything for a extra .5sec that some people say it got far worst reload LOL. Even the older 3BM21 outclasses the T-55AM’s dart by a mile. Add the BMP-3 to the lineup and… what’s even the point? Waste real money in a vehicle that have no point in using.
Do people really believe the T-55AM is anywhere near as effective as the T-62M, BMP-3, T69-II G,tam,xm803 or even the Merkava Mk.1 (which is a complete joke at this BR)? If m60a1 rise good at 8.7br, dont see why t55am not.
Fix the compression. Stop randomly nerfing and buffing tanks while ignoring the actual issue. Because in truth, 90% of tanks feel broken when they’re stomping stuff a full BR lower, that’s the real problem, and everyone knows it. (This is for jets too, jets with no flares against 35g missiles stuff is a joke or BI at 6.7 the real comedy)
