(sorry if this is a bit large, but I am actually asking for advice)
I have been thinking about a "heavy pick" focused melee build while playing the game, having seen a few enhancements and stuff. My first idea was a pure barbarian, but then I discovered the "Critical Rage" line was dropped. Still just the thought of having a x6 multiplier is absolutely insane... I then thought how could I effectively TWF, so I thought taking some ranger levels to get ITWF without having to spend points in DEX. But I was brought back to the pure barb idea because Death Frenzy (FBIII) can increase by 1 your threat range and FBIII itself increases the multiplier. I finally refined to 18brb/2fgt and am in doubt between several class splits (or pure). I have listed the possible splits and their respective pros & cons (in my opinion). Keep in mind I would like to TWF with picks...
20 Barbarian
Pros: Mighty Rage, Capstone
Cons: 7 feats, needs 15 DEX (and +2 tome for ITWF/GTWF)
18 Barbarian / 2 Fighter
Pros: 2 extra feats, fighter haste (15%), Fighter strength (+1 STR)
Cons: Misses mighty rage (-2 STR & CON), misses capstone (-2 STR), needs 15 DEX (and +2 tome for ITWF/GTWF)
18 Barbarian / 2 Ranger
Pros: Free TWF, no need to spend points in DEX (more STR & CON)
Cons: Misses mighty rage (-2 STR & CON), misses capstone (-2 STR), lowest attack speed
12 Barbarian / 6 Ranger / 2 Fighter
Pros: Free ITWF, Ram's Might, no need to spend points in DEX (more STR & CON), Tempest I, 2 extra feats, fighter haste (15%)
Cons: Misses mighty rage (-2 STR & CON), misses capstone (-2 STR), misses FBIII (consequently death frenzy)
