The way it works though, I don't think it can be nerfed. What is mob going to do, have enmity on a player that physically doesn't exist? If they change it to sets the enmity at (value) then superjump could be used to gain enmity from zero. Kinda breaks the system.
I don't really think they're smart enough to make it so all the (half the?) enmity instantly comes back.
Super Jump already sets your Enmity to 1 if you have accrued Enmity, so it could have been possible. Super jump just does nothing if you have no Enmity, though.
But that leads to the second point: do we really believe SE took the time to troubleshoot each ability/trait and appropriately adjusted it? I'm more inclined to believe they did not test much of anything, given the fact that they simply deactivated Yonin, Innim, and Composure instead of toning form the effects.
