Oh get off your high horse
I can't even trust players not clearly marked 1 and 2 to be aware enough to go clear chaos when they're needed to, nevermind mentally following the pattern for orbs. Then you get tanks who aren't communicating overcharges with each other (nevermind everyone else) or the chaos from the moment someone does end up grabbing too late and one of the tanks is dead. And then tanks that specifically yell at someone for either not clearing orbs or clearing them on the wrong time, say, "Hey wait for us to tell you"... and then don't say anything and wonder why nothing was cleaned up.
It's almost like clear consistent communication might actually help a fight get cleared or something. I mean theoretically we don't need a marked priority either, but, y'know, it helps.
