Paladins get 15% attack speed if you devote 31 points into Vanguard. Spending 39% of their action points.
However, Bards can devote 3 feats and get 30% attack speed from Single Weapon Fighting. Spending 30% of their feats. (Or less if they went human or took fighter)
More importantly, Action points are more valuable than feats.
Xendrik Weapons Training gives 2 damage for 4 action points.
Weapon Specialization Feat gives 2 damage for 1 feat.
2x Constitution gives 28 HP for 4 action points.
Toughness gives 30 HP for 1 feat.
Acrobatic gives 3 dodge for 3 action points.
Dodge gives 3 dodge for 1 feat.
Using those benchmarks, 1 feat is worth only 4 action points.
31 Action points is equivalent to spending 8 feats.
