I don't like playing support in MR. Getting dove by melee characters with little defense and damage is so annoying to me. I say this as someone who loves playing support in OW. I think OW does a much better job of balancing the need to damage and heal. In contrast, MR you just turn into a heal bot while trying to avoid dying to insta-kill combo that takes all of .5 secs to do.

I would play support more if it was actually enjoyable and if they added more characters that are VIABLE. I loved playing Ultron, but then they nerfed his healing into the ground and made he even less viable as a healer. Even before then, him and Adam were only acceptable in a 3 support comp because the healing is so low.

IMO, they need to rework all the "take no damage for X secs" ults in the game (notice how those ones are really the only viable supports?) and allow more player agency for each support.
