I copied my 18 barb/2 ftr/5 epic over to Lama to test out some enhancements. I wanted to stay away from frenzied beserker. I'm tired of killing myself almost as fast as the mobs. I focused most of my points in the Horc and Ravager tree, picked up some extra rage and extended rage from FB and OS and weapon spec and haste boost from Kensei. My focus in ravager was crit rage. +2 crit range while raged.
I was pretty disappointed while selecting enhancements. There were a few things that I thought should be in either a general barb class tree or much lower in the PRE trees.
What surprised me was how much better my barb played in game. He was still able to kill stuff extremely quickly, but he wasn't killing himself. I decided to solo an Impossible Demands on EN and it was a cakewalk. Used a couple of CSW pots, but didn't need to. Decided to do an EH and used a few more CSW pots, but really may not have needed those. My toon on live would have had to suck down SF pots to keep up with the damage. CSWs would have been a joke.
The barb class still has a lot of problems like **** saves, but I think the enhancement pass will actually help barb players.
