I've been watching this thread for a couple of days, and am surprised it hasn't gotten more attention. Klepsacovic of Zul'jin pointed out that guild ranks are listed on the armory, and the OP should have checked there. Some people are in the habit of checking the armory for any potential groupmates? I am not, then again, I don't check guild tag either when PUGging. To me bad players can come in many flavors, tanks that don't pay attention to mana, low DPS that are not interested in constructive feedback, loot ninjas, unpleasant people, and anyone who refuses to follow directions or kill order.
