I thought all rangers took quick draw for switch hitting. Even if you are primary ranged, it's a great feat for the option to switch to melee.
People keep telling me this, but the numbers on the switch hitter just don't make sense. Unless I need to constantly move for some reason, a bow always gives enough extra attacks to deal more damage, and spending feats on 2WF would seriously reduce my damage.
Meanwhile, Point Blank Master, at level 6, makes bows function just as well in melee range, and suddenly any melee feats taken earlier become a waste.
(I guess I could mention that the goal of my build was to get Improved Snap Shot and Combat Reflexes as soon as possible, in order to get full-BAB attacks on around 10 enemies per round)
A switch hitter doesn't use two weapon fighting. It uses two handed fighting, which requires Power Attack, and if you want to have a full round worth of melee attacks, Quick Draw, that's it. You don't move as a switch hitter. You stand in one spot, pelting the enemy with arrows until they finally reach melee, and then anyone still standing gets a 2 hander to the face. It is literally the basest of character concepts, and ranger pulls it off easily.
