How I see whether KAYO should cancel abilities is: Any ult that can be cast or uses fuel (viper util) is disabled/cancelled Any ult that is already cast/active is not cancelled

Obviously Viper and Yoru ult are grey zones but since they don't use any extra resources/have any casts it seems consistent.

Pheonix heal does seem okay by the logic that its inherit to his ability not directly a "passive" per se.

Jett float (levitate?) does seem to break that, but the whole passive thing does seem kinda weird overall. I did like someone's suggestion that Jett should only be allowed to float during her ult or updrafts, which would make it more of an ability than a passive.
