Enmity bar is an absolute crap way of judging performance and I wish people would stop spewing that garbage. The BRD who HAS to pop Quelling Strikes in order to avoid pulling threat during their opening burst would look less skilled to you than the one parsing about 200 DPS less with no enmity reductions required. Parsers could also show that WHM with 50% overheal that they have plenty of time to dip into Cleric's and actually contribute rather than Cure II spamming the WAR with Inner Beast and Vengeance up. (Or my personal favorite, Medica II when no one is taking AOE damage...) It could also show you that the WAR is or isn't using those very CDs I mentioned, though to be fair the buff list usually has tanks pretty well covered in terms of performance. Our DRG uses Elusive Jump in A1S as a means of transit from the original Oppressor to .5; do his lower enmity values mean he's our worst DPS? (Spoiler: he's not.)

These forums sometimes man; smh. Bullying people is never cool, but when we have this system that exists to reward people for their positive attitude and/or performance it sucks when you can't actually, y'know, accurately assess someone's performance. (Nobody dipped below 90% HP, so that means the Med II spamming WHM was a really excellent healer, right? ...Right? XD)
