I kind of agree with the sentiment, but this one is tricky. If you DC right after connecting, but immediately log on, should you get a penalty because the party was super quick to kick you? I would think the only case where you should get the penalty is if you DC (on purpose) then come back a few minutes later. The problem is, as far as anyone can tell, those are the same scenario. I'd prefer not to punish users for having an unfortunate DC.

That said, I've been in parties where we all agreed not to kick a tank that obviously DC'd on purpose, and it's hilarious when they come back. I highly recommend it if you're not in a rush!
