That’s a great comparison because thunderclap is more difficult to use than the shove, first being a spell save and second being a full action.
Plenty of fights where it is unavoidable, but as I mentioned in the previous comment, it’s completely different to how it works in DnD and makes some fights a joke if you push an enemy to their death or just causes frustration if one of your spellcasters is shoved to death on the first turn.
Basically turns most fights in areas with chasms into shoving matches which means you ignore the actual mechanics of the fight to just shove and avoid being shoved. It’s sucks.
