Point taken, I did forget about Disease cloud. I most likely wont' get the bertox charm for 3-6 months though, so it's a mute point for me

. The thule charm is very nice though, especially being the only one in the raid with it. However, Ro's appears to be better for AE encounters from the parses you have posted by a little bit. And, giving up that 10% base isn't to bad if you are in the 80-85% range without one of the orbs and the avatar robe procs.
