Great idea, makes Incarnum not an actual headache to manage.

Though, I'd rather not see the penalty of the Spirit Blade, but I guess some penalties must be applied once in a while.

On that matter, why not an Esper Speed? Giving speed then haste and maybe even second turns once in a while? Nothing like time stop, but you get what I mean hopefully. You could give a combat focus esper power, granting increased attack and damage at the cost of other things, such as focus or the weakness of not doing anything that isn't directly combat related. An Esper Armor could help as well, creating a force-field around you for protection.

By the way, warp space could allow for long range attack or violently tossing your enemy through dimensions, dealing damage.
