Regarding the nerf of the air-lunge:
I have no problem in seeing the average air-lunge removed, soooo many "skilled" players relied on that bug to hit people, no fun.
However, there was no harm in the floating bug. It was a bug though, and I think the devs were in their good right to remove that bug. But it didn't hurt anyone, quite the contrary actually.
But, it was quite irritating to see your enemy fall of the edge and then recieve no damage at all, while you fall off and got splattered.
I just fear that the kick will be the new trick to getting around the blocking: 20 damage and no way to avoid it besides dodging like hell.
