What an epic adventure. The hero and the monster shoving each other back and forth. That is how D&D is meant to be played.
someone immediately shoving one of minotaur to death and make the whole encounter immediately trivial is good design, apparently.
There should be a limit to everything, the bigger the target is, the harder it should be to shove them, you can limit it with so many ways and I hope Larian does so. Str should be a limiting factor as should the weight of the object and enemy, just because something is too strong now does not mean it cannot be balanced by release.
There is nothing bad about shoving as an idea, only the execution still needs some work.
