Exactly. The maneuver level determines nothing but minimum Initiator level and Maneuver DC, but if all Epic Maneuvers have a DC set at (10 + 1/2 Initiator level) (which scales nicely, even at Epic levels), then we'd only need the level for the minimum Initiator level...which the skill requirement replaces nicely.

-A +10 Martial bonus to Strength and Constitution. This bonus increases by +2 for each additional 5 ranks in Martial Lore you have beyond the required 30.
