I actually am a support main, just so you know. And Moira is one of my favorite healers to play.
That doesn’t mean I like fighting against 3 support comps. It puts a lot of pressure on my team’s DPS to be able to kill quickly and efficiently, otherwise we just get outsustained, and as a support there’s little I can do about it other than swap to Ana and throw anti-heal grenades at people.
The better solution and the one I’m hoping for is forced 2/2/2. Historically, people have really hated metas where one role comprises more than 2 members of a composition. People hated it with the old triple/quad tank comps that Ana enabled, people hated it with the triple/quad DPS comps Mercy enabled, and people hate it with Goats that Brig enabled.
It’s just not worth it. That freedom to pick any comp you want has caused more harm to the game than good. Forced 2/2/2 would allow for easier balancing on the part of the devs and would ensure that nothing like goats could ever happen again. Every role would be guaranteed to be part of a balanced composition.
