First of all warriors should be able to heal (for a small amount), we need 1 move "Force Drain" (heals for small amount after killing an enemy, last 10secs.) or a strike, that heals us based on damage that has been dealt over the last 8 seconds.
Sure we have Endure Pain, but every other warrior class I've played in other MMOs had other healing utilities, (they weren't overpowered, because it was based on damage, and usually u had to kill someone before you could use said ability).
We need something that gives something to do besides hoarding med packs, or hiding and waiting to be out of combat and use channel Hatred.
TLDR; We Need a Victory Rush
I find it funny that if you read the Wookipedia Article on Sith Warriors, it says we can heal using force drain.... but can't in the game.
