I'm not sure I agree - once you are shoved you have been moved away from the shover - so the shoving character would have to move to shove you again, possibly invoking AoO. I assume if this was an issue, then it would have been highlighted in 5E rules already?
Push in 5e has much shorter distance, and therefore generally doesn't result in instant death. In scenarios like barge combat I wouldnt want to have to succeed in 3 saves per enemy or die.
I am all for making shove more like 5e, but as it is now I feel that making it full action without further changes might actually make it worse.
At least creatures that don't have more actions per turn would probably not do it at all. At worst they would do it once exactly like now.
Shove should just not be available more than once / turn on top of being a full action.Technically, enemy monsters that have Multiattack
cannot use those attacks for multiple shoves. Monster stat blocks say exactly what the monster can do, no more, and Multiattack doesn't say that these attacks can be replaced with shove. E.g., a
Brown Bear specifically makes one bite and one claw attack with it's
Multiattack Action.
The
rules for Shove state that "Using the
Attack Action, you can make a Special melee Attack to shove a creature...if you're able to make multiple Attacks
with the Attack Action, this attack replaces one of them." An enemy Fighter with Extra Attack or Action Surge could shove multiple times, but a Brown Bear with Mutltiattack could not.
Now, do I expect Larian to actually follow this rule if they change shove to being an attack-equivalent action? No. But the correct implementation of shove does, per 5e RAW, prevent most monstrous/beastial enemies from shoving multiple times per turn.
