pvpaissa can give you a general gist for gearing, but their class guides section is sadly pretty barebones. What I do for burst as a war is set up double fell cleave, weaving in internal release and berserk with fully traited full swing during the first storm's eye combo, if they have any hp left a quick mercy stroke will finish them off. If there's a better way then I hope someone else speaks up but try that for now.
