Like I stated later on, if you are doing progress you will need resistance! Coming from pots/buffs/gear whatever. Personally I take about 140 on lavapacks. Tank definitely can't go without it. Also stated when not in progression you can go blank if your dps is geared to the teeth. People claiming yeah we do this without resistance are full of shit or outgear it.
There was also the issue for many in a lagfest witch shouldn't be a problem in this decade anymore.
