Attackers ring. Pal/SK and Warrior might take this ring for additional haste slot. Not that many rings with real high AC, so guess you dont lose a lot of AC .. still .. wouldnt hurt them to put decent AC on these otherwise good items. Even 15 to 20 would be ok, doesnt have to be extreme. A 25+ AC is what I would expect from a tank ring from these zones though.
After all I am wearing a 30AC ring that I got from 2 expansions ago. Seriously, add some AC.
