I'm wondering how feasible it would be to make a half-elf fighter/AA with 18 fighter levels instead of the standard 12ftr/6ranger/2whatever split.

The extra 1 to crit range range from Kensai3 seems like it would add a fair bit of damage of the lower split versions and the 3 extra fighter feats would make up for the ranger bow feats for sure. Or maybe just take 2 ranger as the off class?

Strength based for sure and thinking maybe use a 2hander without all of the 2H feats for time between Manyshots.

Can this work? Is it possible to specialize in both longbow and whatever 2hander?

Thanks!
