2 styles personally
1) heal mode, set pieces from vp set and transcendance set, various crit and overload and power proc jewelry, mythicalm claymore item (oh baby) and executioner signet (untill the fucking buckler from milyex drops) for the otugher fights, big ae fights or any time healing is needed.
2) full burn mode, double attack, dps, haste comming out my ass full offensive, bonecrusher etc etc
i did try mixing and matching but...thought why suck at both wen you can own at one or the other.
now which fight you wear what on dpends on your raid force and the level of players aorund you, but on average trash = dps and named = heal (theres much more to it that that but you have to adjust yourself to your raids style)
result is good

on a good burn mid 3ks is doable in khor sha etc and a lil lower in VP for dps
when healing, well zone wide usually 3rd behind mt healers, without inquisition added in
latest triumph was healing 20% of all damage on a sucessful leviathan kill, 6% above the nearest competitor :p (oh thats gonna get me in trouble haha)
