Do you really need Rage to kill that last single 1hp left Goblin, when its 1v4?

No?
Then good news for you!
You if you will end your rage prematurely, you will get so many Temporary Hit points, you dont even notice you are at 50% so rest of your gear makes you unstoppable killing machine.

Dunno ... awfull isnt the word i would use. O_o
