Meh, not really. She’s one of the more balanced heros. It’s just that there has been a high influx of Orisa players, including myself.
The same happened with Junkrat. After his 2nd mine got added, people started complaining about spamming, but Junk spam has always been in the game, it just took him seeing more playtime for people to start hating him.
Those who complain about her are uaually the Genji/Tracer players who try and destroy her shield with poke damage, or those who face against her on a pirate ship on Junkertown.
Bastion is starting to get that same hate, so don’t feel too threatened.
Balance is not a state of equilibrium, it’s always changing. The nerf to Mercy is a buff to the other supports, since Mercy was so powerful that she overpowered the others.
It’s not so much solely based off subjective experienced, but also data. The problem is that Blizzard is really bad at interpreting their data and players’ feelings.
Mercy was over nerfed based off of player’s feelings, however every nerf prior had 0 effect since Blizzard didn’t want to make Mercy F-tier and upset all of the Mercy players.
