I was bored and messing around with level 60 builds on rift.magelo, not claiming to be a great theory crafter or anything but seems like a pretty solid aoe build. I was trying to get a 3rd soul more involved but Peak of Form and Dark Impulses seem way too good to pass up. Rotation is same as cab at 50 except with Curse of Anarchy in place of Curse of Solitude. I haven't been level 60 on beta so I haven't been able to test out the 61 cab ability to see if its too good to skip out on, it would have to be good enough to outweigh the gain of losing 15% damage bonus to basically all Cab abilities from Dark Impulses.
Let me know if it looks good, what you would change...etc.
