You're kidding, right? That happened constantly.

Edited to add:

In fact, this is the exact reason we did the last 'revamp' such that sets were split up -- people would power to 30, check for one of their wands (let's say aura) from one of a couple sets they'd find acceptable, and delete if it wasn't there.
