OKay these are some really nice ideas!
I think Mercy’s staff should have ammo, it could have 600 hp (Or more) and when it run out her Empower “E” could refill it. (it also can refill on its own, like Rein’s shield)
Yes, Ana and Lucio definitely need some work…
but I think as long as Mercy is in her current state she will always outshine the other healers.
Blizz should work on the other healers, and see if her pickrates even out, if not then… Mercy will need changes
