For some reason I can't log into the official battle.net forums...asks for a cd key and what not which I obviously don't have since its a beta.

Regardless, I played thru the beta on a monk with no issues, now I've started a witchdoctor, and whenever I cast Poison Dart I get half a second of fps stutter lag. I remember watching a video of d3 gameplay a while back where the guy also mentioned this issue...it was so long ago I can't remember what they said about it.

Anyway, whats the issue with this? Is Blizz attempting to fix this or is it some other issue on my side that I need to change?
