But this is alliance roulette though, where it's entirely possible to "carry" statuses and buffs from fight to fight. For example, a rdm could've finished off a previous boss with full gauge and then basically bursts and stays on top of the aggro list for most of the fight because the other dps started off clean. In a 8man raid, yeah I guess you could use aggro meter with greater accuracy but other content where jobs can carry stacks/buffs? hmm, can't say I'd go off with that. Maybe like when we're halfway into the fight but definitely not the start.
