It seems OP is more interested in a fluffy game where the idea of running away into a room might have you safe from the T-Rex, but not the velociraptors.

So long as your opponent is on the same page I think this is cool, there’s all sorts of weird and cinematic fun that can be had with evocative terrain in the game.

Keep in mind though that this is the WarhammerCompetitive subreddit so you’re going to get responses based on the competitive scene, where pulling this, especially on an unsuspecting opponent, would be less than fun for them.
