I'm a fan of the idea, it would be cool if some fights in 8 man roulette were easier with 6 tanks and 4 healers or something crazy like that.

But that doesn't have to be a thing for every fight, its just something that could happen with out a enrage timer or DPS Wipe marker. A lot of old school mmo players didn't have enrage timers on anything they fought or player caps. A bit more freedom in a fight here and there could be cool, more world boss content would also be nice
