Lately I've noticed copious amounts of nightblades stealthing near enemy doors, and then ambushing inside when someone uses the door. Is this allowed? IMHO it's as bad as wall jumping, and if you're going to disallow the use of one of them, then you may's well ban door teleporting as well.
Frankly I don't care. I just want consistency and clarification before anyone else gets permanently banned for an exploit they weren't aware was an exploit.
