Most everyone is in a hurry these days, always late for something. Aint got no time to follow silly numbers. Anyways, I don't even bother marking and no one really says anything about it. If people want to run ahead, go ahead they may just die and get angry. Hardly anyone sets any game plan or whats expected at the start of dungeons. Even if you do most of the time there is no response.

I think for the most part most people will just watch what you pull first, then go down the line from there. If its a stronger monster or has an AOE I'll hit it first. I'm always cycling through the list anyways to keep the healers aggro down. Haven't really had any complaints so it seems most people are ok with it.
