Moonstone Spider said:It would be unfortunate if double weapons couldn't get advantage of this feat, from a balance perspective most double weapons are greatly inferior to a normal weapon twice anyway since:
a: You usually have to take an exotic weapon proficiency, burning a feat.
b: Almost no double weapons are finessable, which sucks since you pretty much have to blast up your dex to get the feat to use them and now one use of that dex is wasted.
