Well, it's fun, provided YOU aren't the one getting shoved into Lava before you can even take a turn - or YOU aren't the one getting shoved off a cliff in the Underdark and sent 300+ feet into Torchstalks WAY down the path from the spectator almost to the Arcane Tower.

So, I have said it's not a fun mechanic, but only because of how ridiculous the distance is. If it was a Bonus Action and only shoved 5 feet, that wouldn't be a big deal to me. Even 10 would be acceptable. The issue I have is mostly with the crazy distance.
