Yeah it's a godly powerful move but you need to sprint uninterrupted for 3 full seconds before you can use it. Also. If you sprint for too long it expires and you need to stop and start again. I originally thought I could sprint around the map tackling guys for easy kills but it's quirks hold it back from dominating too hard.

Errr I guess thats what you said, I never said it was OP or anything I think all abilities have weaknesses and strengths just like all weapons, can't fire from a distance with most assault rifles and can't mow down a lot of thralls with a scout (well you could but it's a bit harder)
