Victory Rush was enough for me in the low levels...
Oh, it gets you by. I'm just comparing to other classes I've played at low levels.
Pre-10, if I had 3+ mobs on me, I was in trouble (mostly because of the lack of available attacks after I'd blown VR).
Post-10, I'd pull groups of 4-5 so I wouldn't get bored, and come out with about full health. The jump in power was staggering.
