This may not be the funnest thing to hear. But yes. Absolutely moira IMO needed to have been nerfed.
Im not a "pro player’ by any means, but having to play around a moira in Quickplay games is insane. Dealing with over-tuned supports is a big issue that people have complained about for YEARS. Especially “Moira”.
The man himself Father Kaplan even jokes about it on stage at Blizzcon that his nephew wanted Moira Nerfed or “deleted” and rightly-so, the “social expectation” of supports are to be “heal bots”.
Many people that have mastered the playing of a support character will say otherwise that they should be “what they are, why they are”.
However, on the other hand. We see them as “raid bosses”. As they have high sustainability under heavy damage, often times abandoning a role which is needed, which is “healing”.
Anyway, its controversial. Im not saying Im right. But I do feel like nerfing moira into the ground is very fair. and if not they need to be nerfing the healing output and passive health regens for supports by a alot.
