Honestly stack feral druid tanks, ret pallies and roll multipriests. This current “meta” of 1 prot pally 1 ret 1 holy is just dumb. having 2 coh or 2 shadow priests is a game changer and nobody can tell me otherwise. Reject metas that only work for a small % of guilds.
Stop trying to copy 1 night 14/14 speedrun guilds with 3x your dps. You cant do fights that way unless you have the damage for the healers not to oom because the fight only lasts 2 minutes. I find lots of issues with guilds trying to minimally heal with mediocre dps, its not viable.
