BrM without weakaura ? Nothx
Same with my retpaladin without something to track inquisition.
My enh shaman could probably continue without addon.
Without blizzard deeply improving how shitty buff/debuff are in the default interface can't see this happen. Without even talking about healer interface (the only characters that have a raidframe addon are my healers)
And for raid bosses encounter, blizzard allready said multiple times that they are designing boss fight with bossmods in mind. So I rather prefer harder boss with addon than easier one without.
