@Teniel: If you look at the advancement plan, I'm intending to get rid of that at level 4. I took it so I don't have to wait for Dazzling Display and the performance feats I want until after level 3.
As to Deadly Agility, I may take that at level 3 when I get dex to damage anyway from Rogue. It's worth +3 damage for half my attacks, which isn't too bad, but I'm still not sure if that's a payoff worth investing a feat over, compared to, say, Weapon Specialization, which is +2 damage to all attacks.
