Enraged Slash, in the first tier of the Annihilate tree for Sith Marauders currently lists it's rage reducing mechanic as a "chance." For the first two points, @ 33 and 66%, the chance makes perfect sense, however at 3/3 the 100% chance does not work to what I believe to be the necessary level. As it stands now, yes, Vicious Slash and Massacre, cost 3 each, 2 rage with this talent. This issue is that when I have for example, 2 rage left (and with 3/3 ES it should only cost 2 rage) i can't use Vicious or Massacre. The same thing when I've got berserk up and 1 rage left, I can't use Vicious. My suggestion is at 3/3 Enraged Slash, change the functionality to just reduce the rage cost of the 2 abilities by 1, as opposed to a 'chance to return' rage.
