Stats for the lazy:
-1.72 Attack Speed (working on getting this up, without sacrificing to much CC)
-50% Crit Chance
-149% Crit Damage
-+20 Arcane power per crit
I am consistently getting stomped on by any elite pack I run into in Act 3 on MP0. I just cannot get enough critical in to refresh diamond armor fast enough to live through desecration's or arcane beams when they hit. The worst are the ones that teleport away when they are unfrozen and beat me down at range (succubus's)
How I go about engaging an elite or elite group-
-TP to the middle of them
-Cast frost nova while starting to spam my energy twisters
-Hit diamond Armor
-Start spamming buttons and twisters until I die or they do. Sometimes teleporting away from desecration's if I notice them in time or teleporting to an elite that escaped.
Edit/Note: I do not seem to have any problems taking on elites on MP0 or MP1 with a 4-man group if that is in any way enlightening.
