Agreed - shoving is over-used and overwpowered when compared to 5E. I have also taken to using it since it's used on my party constantly. With the verticality in the is game it is often deadly. As for waking sleeping characters with shove, that is simply broken - use the same 'help' action that PCs use to wake a character. It should cost an action to do that - so you sacrifice your action to wake someone who may otehrwise be killed etc.
