I think DBM dumbed ppls, i got countless wipes on different encounters just because my guild raiders complain their dbm counted wrong on their debuffs or spells or w/e
when they could have just looked at the cast bar or debuffs or w/e.
OT: i use standard ui too and i like it because it's clean but i also use recount and few other addons but no addon for design or to change my bars.
