Same here. In D&D two weapon fighting is NOT worth -2 to hit, two feats, losing shield bonus, plus having to find 2 magic weapons, etc. All the games i've played in made Ambidex and TWF one feat, and it still sucks unless you have Sneak Attack dice.
I don't agree with this, it just takes longer (and a lot of feats) before TWF starts to pay off. But when it does, it can get powerful. The only real downside, as I see it, is the need for the 2nd weapon, although things like GMW can offset that. A 16th lvl TWF gets 7 attacks per round at -2 to hit compared to the 2HF's 4 attacks. The 2HF can put those 2 points into power attack, but the TWF has 3 more chances at critical hits (plus the damage from those 3 additional attacks).
A figher with greataxe can have Power Attack, Cleave, Weapon Focus, Weapon Speacialize, Expertise, for the same investment as your TWFighter.
The TWF gets those same feats, he just won't have them at the beginning. That's part of the whole "it takes a while to pay off..." thing.
1st lvl: exotic weapon, ambi, TWF
2nd lvl: weapon focus
3rd lvl: power attack
4th lvl: weapon spec.
6th lvl: cleave, expertise
8th lvl: improved crit
9th lvl: improved TWF
10th lvl: OPEN
12th lvl: power crit, OPEN
14th lvl: OPEN
15th lvl: greater TWF
One of those OPEN slots could be this Improved Ambidexterity feat, which apparently gets rid of the -2/-2 penalty. Now the 2HF can use all those TWFing slots on something else, but there's only a handful of weapon-related feats, and the fighting feat chains (power attack, expertise, dodge, etc.) aren't always open (because of stat prereqs). So in the end, the 2HF is more flexible (more fighting styles) but the TWF gets more attacks.
