So I'm giving this a REAL good shot, trying not to be too hasty on judgment, but its very hard. Stasis is more crowd control, it seems more intended as defensive, so I understand why its lower damage to a degree, but because of this, in order to get these 10 kills required, you literally have to time it JUST right to get the kill, with two other people simultaneously trying to kill the same enemy, and well, 99% of the time you miss out. One fully used super doesn't even take out these champions. You've set a goal that is FAR too excessive. The best way to fix this is to just change it to "defeat champions affected by stasis" that seems reasonable.
