[QUOTE=Vargouille;5333501]We're currently leaning towards making THF and SWF mutually exclusive, with the current versions of the feats.

I believe this would be overkill. If the problem is the six feat investment and Dwarven Axe or Bastard Sword glancing blows then regulate it don't eliminate it.
Two alternatives to a flat out ban:
1) GSWF and GTHF are mutually exclusive.
2) Dwarven Axe and Bastard Sword (and possibly Warhammer for theme) gain half melee alacrity from SWF line (ie +5%, +10% and +15%) as really they are hand and a half weapons.
