two said:That's it. It's really pretty basic. The sword-n-board guy gets better AC for less damage. The 2-handed weapon guy does big damage for less AC. The 2 weapon user... well, as it stands currently, he gets to have a lower AC and do less damage than either the first two fighting styles. It's like, huh? Just seems silly to me.
The two weapon fighter in my campaign (on course to be FTR16/ROG4) admittedly had all of his feats based around two weapon fighting, but I have to say that his damage output was absolutely equal to that of the high damage dealers (at least at 10th level it was, we ended there). And he had a higher AC than anyone else in the group. The only time he ran into any trouble was against enemies with high DR.
The only house rule I put into place to get him there was to allow Two Weapon Defense (and upgraded versions) to work with Combat Expertise (when 2 or more points are spent) just as if the character were fighting defensively.
