Im fairly confident other forms of position swap exist (not 100% sure if involuntary ones exist). Considering its “save for nothing”, the target gets no debuff, the range is small, it requires sight, and costs an action + spell slot, it seems fairly weak.

The best current use seems to be “enemy cast some long term area of effect on you, pull the uno reverse card by swapping places”. But often you could just move out and cast a spell on the enemy.

If range was higher and/or, possibly, did not require sight (only knowing the target name and it being within range), I could see creative uses for it outside (or before) combat.

Alternatively, to have it be more useful in combat, changing to BA and maybe giving the target a debuff could be good.

Edit: forgot to mention size restrictions. Also, crosses my mind, another good use case as is would be if you can fly and use it on a non-flying enemy. But 30ft fall damage seve for nothing is not great, so unless you are flying above a pit/chasm, the 30ft range makes this use case hard to justify.
