Talon's parkour should not cancel his ulty and reveal him.

yea I noticed that in PBE, while assassins were in the process of being changed, if you Ult then try and vault over walls you complete leave invisibility, kinda of a awkward feeling and I'm not sure if its intended or not.

i don't play him but i totally agree with this

It breaks his invisibility because he isn't supposed to be highly mobile while unseen. He can't be detected by Control Wards for his ult, so he would be incredibly busted if he could gank the lanes without any forewarning.
