Yeah he really should be. I actually thought since I was floating that I would float right over it.... because most of the game has decently real physics.. BUT NOoooOoooo... It snagged my air. Caught me right on my AIR.
Reaper used to eat souls souls to get life back before his lifesteal rework was done. there are some things you simply have to suspend disbelief about in order to balance the game.
I totally agree, it would be a very interesting counter. It's like how some heroes can get out of Grav, Orisa can become immune to CC, or D.Va/Genji can negate ults. Plus it makes much more logical sense since he literally floats above the ground.
thats the problem, though. it would be TOO helpful. its not balanced to give him that immunity. its why ill regularly spring a junk trap a second or so after popping my ult.
