Actually, every hunter under lvl 25 loses concussive shot. I would consider that a nice nerf(should of been like that in the first place)Damn that's cool. His focus bar isn't even dropping.
This will probably be the next buff hunters receive - something like: all hunters under 25% health get 2310% haste.
Should have used Aimed Shot imo. That much haste would easily get you down to the 1.0 sec gcd minimum, and you seem to have had enough focus regen to allow spamming.
Very cool vid.
