Shove is hilarious, and at this point its as iconic to the game as barrelmancy is to dos2, it should not be changed under any circumstances
Glad you like it.
The problem is not about it beein hilarious but about it breaking the 5e combat rules. That, it seems, is what larian does not want to accept exactly because they and people like you put the "hilarious" factor over the functionality of the system. That makes me sad.
The downdsides to what you call "fun" have been explained in a lot of threads. Including proof.
