The Arcane Marauder path for Spellswords gives Weapon Specialization at 14, Power Attack at 21 and Epic Weapon Specialization at 28, while most Marauders would feel like there are no problems here, I see a glaring annoyance in the Power Attack feat, it is gained in epic levels, which means those going Overwhleming Crits would need spend three epic feats (cleave, great cleave, OWC). Now, this might had been for balancing purposes, but I feel it extremely redundant as anyone building for OWC will take Power Attack and it's prerequisites pre-epic feats before 21, rendering the free bonus null. Such a thing only happens to Arcane Marauders since it is the only path for spellblades that gets a prerequisite feat like Power Attack, at level 21.
For the purposes of not having what is essentially a wasted feat, I propose shifting Power Attack over to Level 17 instead, so those that do wish to go OWC still have leeway to without wasting a bonus class feat, or changing the level 21 feat to Epic Toughness instead, since Toughness itself is a prerequisite for this path.
