I'm confused as to when the damage dice get recharged. Reading the class pdf it seems to imply that your damage dice get recharged every turn. Specifically it says "When you spend a martial damage die, you cannot use it again on the same turn." However many of the Maneuvers, like Protect or Deflect Missles, dont take place on your turn. So if you spend a damage die to Protect do you get it back for the next Monsters attack? Could a level 20 defender spend all 6d6 to protect one of his allies on every enemy turn?
