This raging powerhouse of death dealing that necessitates nerfing?
I picked up the tree about a month ago, and have 4 characters using it, with different classes and the like, and so far, I'm not seeing it.
It's decent, but so far, it's not any better than a repeater Arty or a great-xbow mechanic. Actually, I would say it's a wee bit behind a solid repeater build.
Or is this one of those things that's only Bill Bad Butt when backed up with a ton of past lives, epic past lives, and reaper points? If so, then every discussion about it is moot since the game shouldn't be balanced around those conceits.
