Thanks for the reply.
I heavily considered going two barb instead of two monk. The rages do fit in nicely on a burst designed build. If one were able to fit in PLF: Barb, then it could really make sense, but the feats are very tight already.
Losing two monk you'd have to scrap extend (meaning losing ~6 mins of +3 to hit and damage per shrine - livable) and toughness - harder to give up on this build that will top out at about 630 hps. Of course the rages would make up for some of the 63 hit points you'd lose with toughness, but again very limited duration rages. To fit in PLF: Barb, the next logical feat to drop would be ICrit: Ranged... now I'd be canabalizing the build somewhat. Also, the fact that they have said that the PLF: barb is not working as intended with stacking str and con makes me very hesitant to TR a barb life just for the feat.
Another thing I considered is that while on paper barb rages add a couple more points of burst damage, in my experience in real in game application it is impossible to get the timing of short rages and re-casting of Divine Favor/Ram's Might perfect every time especially with Madstone thrown in there, resulting in actual lost DPS. Having a 12 minute Ram's, and a 4 minute Divine Favor leaves much more room for getting one's timing perfect.
Evasion. It's nice to have, but like Nick, as the game matures I feel it has become less and less requisite on builds. That said, there are times, like tanking Chrono epic, where it's very nice to have it.
A logical case can certainly be made for two barb levels, but in the end, for me, monk is the superior choice.
