Knowing how long to hold down Quick Rebound is essential to its use. Don't say it sucks just because you're tapping it and getting owned after your 0.3 sec invincibility; you're not using it to its full potential.
Okay, now I know Quick Rebound has more uses than what I give it credit for with the full second invincibility. But if you're already strained on SP, I really don't think it should be a top priority.
