When I cast the spell Shocking Vortex on raids, I almost always get a message that the spell has been overwritten before I can even cast another spell. Anyone know what is causing this? It doesn't tell me what is overwriting it or why. Seems stupid to spend 1000 AA's for the Evoker's Synergy, only to have the spell instantly overwritten. It's bad enough that the 25k AA bonus doesn't work on fire nukes, but then you lose the improved damage from the spell that effects the caster only.
