At the time of making this comment it's actually been maybe two years since I last played Overwatch but man I remember this so well. Classic case of "it's fun when I'm Sym but annoying when I'm not." Similar deal in TF2, love it when my sentries get kills when I'm playing Engineer, but when dealing with enemy sentries it's like I'm practically forced to switch to Soldier or Demo because no one else on my damn team wants to change to the proper counter.

This exact scenario just happened to a teammate I was trying to heal. Sym drives me nuts.
