ShooshFirstly, for people saying balancing isn't need, you're blind. There are so many overpowered things in this game.
while i agree there can be balancing changes made, a lot of those problems you list seem to just be inexperience vs playing those characters
i had a hard time against double mei strats, but i didn't feel like she was really overpowered tbh, she's really irritating but it's not like she's invincible and you can still zone her away by just shooting at her from range
imo widowmaker just needs to be made so that her ult only affects her over giving the entire team wallhacks, i think that would be a totally fair change to something that is already ridiculous. also i've used her traps to kill tracers/genji and things chasing me so many times that it's ridiculous, saying her poison traps are useless is just wrong imo
i don't mind bastion because he's countered by a handful of things that can take him at range or pull him out of his sentry mode. the only real problem i've had is playing against him when the entire team is damage buffing him + placing shields to protect him, although that just leads to the ability to attempt to get around their team and flank a greater threat
i feel like genji reflect is just inexperience, i always try to wait for him to wantonly pop it and just bodyshot/headshot him for the kill since he can't do anything but blade dash away or try to kill you, if he runs he's dead. i feel like it's really easy to abuse currently just because so many people are trying the game out for the first time, i was tilting pretty hard on day 1 when getting killed by my own reflected headshots, but after i learned to just wait, he hasn't been anywhere near as irritating to play against
mcree is really strong, but i wouldn't say his flash is the only reason he's so strong, he just outputs so much damage at any range in both solo and group fights lol, i wouldn't be able to think of a nerf that wouldn't make him completely useless though i think he shouldn't keep 50% of his meter for failing to trigger his ult
i haven't had any qualms about melee range guns having autoaim in regards to winston/symmetra
imo i think meter should be drained when dying, but switching heroes should have no penalty in regards to meter
i'm definitely going to post the same feedback in the beta forums, but i think it's stupid you can wipe a team and their mercy comes out of nowhere with full meter and just revives everyone after you've been killing her over and over
edit: i made a large post about the ults and i think the entire post got deleted because i mentioned i'm a tf2 player, unless each post is moderated before posting lol
