Well what about for less of melee/caster viewpoint as much as a straight up killer/survivalist. When comparing fists and staves, is the difference MASSIVE? Like double? or is it like 20% more damage? whats the comparison between unarmed and quarterstaff when no feats are invested?
Another thought when it comes to survivability....what's the difference in attack speed in the two attack forms? It might matter when FoL is involved. Obviously unarmed with TWF is going to be faster...but how much faster?
Also consider the huge stat investment to get to a 17 base dex for Itwf...
