@KDubya I accidently posted while I was still typing.
Most duel wielders will be dex based and if they are str based and had the choice why would they choose duel wield over 2 handed weapons?
I have a str based heavy armor Ranger/Tempest Cleric that dual wields since Rangers don't get Great Weapon style. The str and heavy armor go well together so dex is a 10.
For a dex dual wielder the feat probably is not worth it, Savage Attacker is probably better.
A two hander with GWM will outdamage a dual wielder but sometimes style counts for more than pure mechanical advantage.
