I've tried to keep up to date on each spec and although I enjoy GS, like alot...I prefer it over the other two even if its not optimal, because its fun and hits big which is all i really enjoy. I think that fire is okay though...been practicing it all night and finally got a burst kind of rotation down atleast on raid dummy. So Ill be going arcane fire probably.
There's a glimmer of hope for AOE because the sims were erroneously not using Comet Storm at all when the talent was selected, but I haven't heard any high hopes that it will be op.

No go. I don't see it giving any considerable change when it's used.
