However, the real kicker is the fact that TWF benefits from most buffs twice as much as THF. The fact that bard buffs, divine favor, prayer, and most other straight damage enhancements give a double bonus to TWF is what pulls it firmly away in this game.
When comparing unbuffed, vanilla fighters, THF is pretty darn good. It's just that that's not typically the standard in raids.
