I am good with my masteries and skills, and I am looking for suggestions on passive's . I currently have Crit and intelligence maxed and was wondering if any other passes are worth investing points in. Is it worth putting points into another passive or more so in masteries, What gives you the most bang for the buck?
I already have timeshift maxed and 3 in fireball for masteries.
Generally I am looking to do Max damage. I have lightning fireball timeshift and gust.

Thoughts?
