No, this PTR patch is totally underwhelming.
Roadhog got no changes to Take a Breather, Reaper got no changes to Shadow Step (the worst movement ability in the entire game), and Mercy will still be the worst healer in the game.
At first, I misread and thought that her base healing was increased back to 60 health per second, but then, I realized that’s just during Valkyrie.
So, Mercy’s Ultimate will allow her to heal just as fast as he could before. *sigh*
Her healing when not using Valkyrie will still be painfully slow. I never feel like Mercy is actually able to keep anyone alive while they are in combat. I have to stand there for about five seconds like a statue since her healing is so slow.
