Big shoves on enemies is fun but can feel unearned when you can just do them without any kind of resource or skill or stat expenditure. Enemies using it on the player is pretty infuriating and there is some balance weirdness to handling large groups of enemies any one of which can just dash-shove the player off something tall and there's not much counterplay. I don't quite know how you'd balance it to drop the feels bad moments without sacrificing the feels good ones but there's already something of a framework in Shoving attack, Eldritch blast, Thunderwave et al.
