If you become an EJ Benefactor, you can get a blog on which you can post stuff like this so that everybody can skip reading it.
Yeah we finally downed Vezax after nearly a full night of attempts and FG/EB was a solid performance. The FG doesn't go OOM cleaving the duration of the fight (which was my original concern with a pet-based spec) and <1sec casts on incinerate/soulfire is flippin retarded. You can pretty much 1:1 weave from any distance if you're in the shadow crash. However, threat kind of becomes an issue if you spend a lot of time in shadow crashes early on in the fight.
And full demo does sound very very good, I'll try that next week.
