Mercy is in almost everyone's top 3 characters played this season, Mercy is a must pick for support and if you take down their Mercy you basically win the fight. Overpowered. PTR changes are good changes. I don't mind her new Ult but again overpowered and shouldn't have released without proper testing.
I'm glad mercy is in the meta because when I play Winston with my Mercy main friend we can dive in and because he actually knows how to not die in a team fight we charge ults faster than a Genji with all the powers of God and Anime on his side using a strategy made by a team of coaches headed by Daddy Kaplan and Seagull
I main mercy and I kinda agree, regaining her health during her ult at that fast a rate whilst being able to move like she does, is unfair to say pharah who has to stay motionless mid air... there's counters like mccree and soldier but being able to stand point blank range of a turret and treat it like nothing more than a scratch is a little over board compared to other characters mid-ultimate. The changes are good just the balance isn't quite there.
I'm mad because I don't know how to counter something, so I can't wait until the game's skill floor lowers so I can actually play well instead of be forced to adjust and improve.
