I have been using arena unit frames and x-perl (for focus frame). Along with those I have Zhunter, a distance finder, and icu (for map pinging to find out enemy units type).
What do you all use? I was looking at PitBull, Natur EnemyCastBar, and OmniCC on the curse gaming site under pvp section. Any of you ever use these and if so how would you rate them 1-10?
