When's a good time to pick Mercy over Zenyatta? Hi everyone. I main Mercy and Zen in all of my competitive matches (200 hrs Mercy, 200 hrs Zen so far). Usually I just pick one of them according to what I feel like doing in a match. When I want to output significant damage and destroy while healing, I pick Zen. When I want to heal much more than normal and assist teammates with damage boost while sometimes dealing a surprising amount of damage, I pick Mercy. Currently I find Lucio not too engaging or fun to play and I've been avoiding him till the changes go live. So Mercy or Zen are basically my insta-lock picks in every game. Any better rule of thumb  that I should follow as to when to pick either one of these supports? Thanks in advance!
