That's my current build i'm using right now, ~1.5m damage 10m toughness but it really doesn't seem to be doing as much as a conflag build, was just wondering if i should be swapping around some passives or run archon instead of a generator etc, any help would be appreciated thanks!
you are most likely running out of AP way too soon. I did a quick look @ your gear and stopped counting AS @ 31. drop all or most of your AS, get your APS down to about 1.5~1.6. at that point your should be able to sustain your AT. I am only running AS on 1 piece of gear on my wiz and t3 is a breeze.
