Shove is really fun as it is. Literally every single person I've watched play BG3 on Twitch or YouTube (and it's been a lot) has been utterly delighted by Shove as it is. Even if it unbalances things (literally, am I right?) some, it's so entertaining I don't think they should change it.
Changing the action economy has very little to do with the "fun" aspect of it. The shove would still be the same as an attack action, you just wouldn't be able to attack in addition to pushing someone into lava, or doing an "I win" push off a cliff.
While cutting the ridiculous distances could have a more of an impact of someone's casual fun, shorter distances need to be enforced on harder difficulties where players are looking for a more serious challenge than just abusing the same overpowered cartoony mechanics.
