(sigh) let’s edit this again!
Let’s start this off with a disclaimer: I’ve already switched heroes and am playing a much wider hero pool. I still miss the fun of old Mercy, and would like to add her back to my hero pool.
You can accuse me of “just wanting her to be op again”, but what I really want is for Mercy to have a much higher skill ceiling than she currently does. Right now you can only really master her basics, since E-rez is so black-and-white on how/when to use it , and Valk does all the work for you.
There used to be an entire extra dimension of strategy for active Mercies who split their time between running for their lives and planning out when/where the next tempo rez would be needed. I’m disappointed that the devs didn’t even try to rework ult!rez before deleting it… in favor of an ult that they had already tried during alpha, but originally decided against because “it didn’t feel like an ult”.
In the end, it’s the drastically lowered skill ceiling that’s made Mercy so uninteresting to me. A big fun factor in this game for me is the concept of and perusal of hero mastery.
