The one problem I see with Limber is this:
In the cases of Shield Mastery, Tactical Parry, and Tactical Guard there is direct contact between your shield/weapon/fist and the enemy which is where the TP comes from. In the case of Evasion, there is no contact thus nowhere for the TP to come from.
It would be cool, but unfortunately, with how TP works, it does not make sense.
