A SELF-"Grounded" Ability is Needed

With displacers like these, it'd be nice to see a self-cast "Grounded" ability state on some tanks (DEFINITELY NOT SQUISHIES).

EX: Self-cast grounded ->> Hook hits ->> Either nothing happens OR the champ casting the hook gets displaced instead.

Alistar would get knocked back by his W, Blitz would pull himself in with Q, Pyke tosses himself with Q, Naut.. travels the whole way?
