the build is alot more fun to level up if you get the barb levels out of the way first. I'd probably do Rog/Fighter/Barb and pick up the PL feat, then another barb level or two, then rogue and fighter again, then finish out all six barb levels before doing the rest in fighter.
having the PL feat pretty much means you'll have more rage time than a pure barbarian of the same level, and thats not even counting the fact that you'll have 4+ levels tied up in other classes. But then again, you re able to dual box with a caster, so level progression isnt a real concern.
honestly tho, I cant seem to decide between doing this build again upon hitting 20 in the next few days (which would make fighter life #3), going ahead to my (hopeful) eventual end build of a barb with 18 or more levels, or going monk
I'd like to be finished with this TR business, but I'm still too fed up with the state of barbarians atm to play the character I originally rolled. And while I like this level split, it just feels horribley gimped compared to a prenerf 20 barb (thats with THF atleast). I'm in the process of crafting a few TWF weapon sets for the eventual end TR; and I think that TWF will give more oomph to the build, as recieving zero glancing blows due to active combat has really shortchanged most of my current weapons. Theres only two things I really dislike with this build (formally known as an archon build BTW)
1: signature weapons, less of a problem on a multiclass than a 18+ fighter, but still, I hate feeling subpar just b/c I'm not using a particular weapon type. I'd like to spec both khopesh for bosses and picks for trash and be optimal at both, not just one.
2: haste boosts and power surge, so much of the real DPS of the build is reliant on such short duration effects. Sure when haste boost is going, the build is just rocking. But being so dependent on something so expendable is disheartening. I either burn thru them too fast, or end up not using them at all. I could never find that happy medium with it.
so it'll be a khopesh and pick using barb I think, or a pure monk for the time being. The downside of the monk being that alot of my toys will end up collecting dust in the TR cache
