Upon further thought: POWER ATTACK???? Why that particular feat? Why not Martial Weapons or something, or Improved Critical? At lease open it up for those Bards who took a level in Fighter or Ranger and not just Barbarian. That would make more sense to me... Not all Battle Bards are 2-handed weapon weilding Bardbarians, some of us actually like to go sword and board...
My Battle Bard took a level of Fighter, uses Dwarven axes and sheild, has weapon focus slashing so he could get Improved Critical slashing (why is that anyway? it doesn't indicate there is a pre-req for Improved Crit, yet there is???). I have no desire to pick up Power Attack at all! Sillyness...
