Maybe instead of blocking the attack completely once per round, the barrier provides a boost to evade for the first projectile attack the kensei recieves. per round. This gives the Kensei a bit more survivability, but doesn't entirely negate an attack each turn.

Alternatively, the barrier could just cause attacks from non-bullets to glance.

Another idea i had was to allow a kensei to get additional charges for the ability by spending momentum. That way the kensei could choose to tank projectiles jedi style at the expense of not being able to perform other actions.
