Suppose I am TRing my barb twice to a 36pt build with 2 past life barb feats (10HP)
I am now considering on whether to go pure barb (benefits of +2 STR capstone, glancing blows, +2 STR Mighty Rage) or to go for a fighter/barb build with 2 extra feats incorporating the frenzy barb feats i.e. (+20HP, +2 Intimidate, 30s stacking rage) x 2 = 40HP, +4 Intimidate, 2 rages, as well as getting fighter strength, and lvl 1 haste boost.
Im not sure if the 60HP benefited this way is better than the capstone, and I'm guessing it's not.
Another way is maybe to go 18/2 barb/monk to get evasion, and fit the power attack into monk, freeing an extra feat for the past life. Then again, not sure if evasion + past life > capstone again.
Im leaning to pure barb from experience, my gimped previous life pure-barb seems to own my 12/8 fighter/barb lol.
