aye.. having one of the procs be ineffective sucks.
for a while, I was having to use one potion/kill. Now (more avoidance & few more defensive AAs), its lot better. All of the spell aas were capped by then.
Getting your proc dpsing again will help a lot and of course the wonderful wonderful taps ;p
while tru that the healing aas wont help you dps as hard, it will lessen the time that you have to spend healing yourself.
I do tend to kill the first few mobs pretty quickly and then start to slow down into a groove with slightly slower kills, since I tend to burn thru mana a lil fast on first few, and then just go into ostrich mode (turn on attack & look away) when I hit 2m so I can med it back up again.
