Might want to add those white mages, summoners or machinists who constantly push the monsters away from the group. Everytime the cooldown is up WOOSH away from everyone else just because they can. Rather than have Garuda (or carby if arcanist) on obey (I have her on obey mainly for that reason), and push mobs towards the tank or into the crystal light in Darkhold (situation where fluid aura is actually useful). These poeple ignore the fact that they draw monsters away from the tank's reach and also interrupt casters when they have that particular mob targeted and casting a spell. They just spam it everytime it's up, well, because it's up and they wanna look busy doing stuff.

Also I agree completely on the polite thingy. No excuse at all to not say a simple hello at the start of the duty. We are people after all, do you do that in real life too? I don't want to be your friend either, and chances are, we won't meet again. But for that run, please don't be so rude. You guys who do that, don't realize how lonely you make people feel like this. I don't want to marry you, I dont want you to tell me your life story, I dont care if you remain quiet the rest of the run. Just a little hello or /wave. And if you have a bad day, saying hello and being greeted back actually will make you feel better. You will have new temporary friends that will disappear from your life as you click the exit, so you have no responsibility towards them after. Saying hello doesn't tie you to anything. It's basic education towards others.
