the game was almost balanced before brigitte’s release. and instead of nerfing her, they just trashed so many other things. because they reeeeaaallly dont like nerfing the heroes that mercys can actually play. of course, there was no way to fix the game without hard nerfing brigitte. but they only did so after buffing moira and mei.
of course, we will now be stuck wth OP easy mei and moira until they come out with something else OP and easy for the mercys to play. meanwhile, they will nerf Orisa instead because they dont care about tank players, and they’ll keep buffing the tank counter DPS for the same reason until they force the meta to shift without actually addressing the real problem. and the cycle continues.
the game is in its current state because of the tank counter DPS (particularly mei) and because of moira’s insane healing numbers.
by nerfing mei, the tank roster would open up and Rein and Winston would be allowed to counter Orisa again.
by nerfing moira, the flanker roster would open up and they too would be able to counter Orisa again. tracer and Pharah have always been significant Orisa counters.
Sigma is marginally too strong, and his ult is the first place to look to. splash damage is usually toxic, so that can go too without removing anything from his skill ceiling.
with the OP easy heroes dealt with, we can see how the meta shakes out. If Rein and Winston are still too countered, take marginal power from Reaper and Doomfist.
widow and hanzo and EMP and blade are still issues, even if other things are more OP. so explore those options as the next step forward.
but mei and moira are the real problems. just as has always been OW problems. makign heroes that easy that strong will obviously break the game, because there is no margin for error while everyone else DOES have a margin for error. and making a simple hero with simple mechanics as strong as heros with versatile mechanics will always break a game, any game.
