For the belt/cloack it's up to you, for talis just go armor/thoughness whatever you want/cheaper

If you want a tip, just dont go into the zerg like a madman

If you run 2 range dps just KB the target and try to KD his guard ( if he doesn't have immunity).
If you run 2 melee dps just KB the guard and KD the guard in same time (if you can, and no immunity as well)
If you run 1 melee / 1 range dps same strategie as 2 melee.
And also, if you can try to stagger/KD healers ( Dok should be the first! He can only cast Hot/abso/clean during KB which is not powerfull when a good focus pressure

Hope it will help you, even if im not a master of this class
