If they keep it that way, they seriously need to have modifiers to who ist shoving whom or what.
If a halfling suceeds shoving an ogre, he should fall down max. Other way around a little flying would be ok. I mentioned a little awkwardly above, but the physic part about relation from size/weight and strenght needs to be changed. Even if they make it a full action.
And i hope they change jumping too. Having dwarves in full armor jump around the battlefield like frogs is really cringey.
