As a healer main it's frankly maddening how often my tank runs off to one tank and the entire rest of my group just mobs whichever tank is the 'main target' leaving me to excog and aetherpact the tank and then do my best to keep them up while they inevitably get nailed by all the aoes, then go back to spamming my tank who is half the world away... before the mob shifts their way. Rarely does it play in my favour. And it's exhausting. Or sometimes the raid group fractures and splits up and I get to play 'where is everyone? Guess someone is gonna be unlucky toniiiiiight' and hope my cohealer has gottem because if you're outside my aoe-heal range at that point? 'then perish' comes into play. I am just not going to chase you down to heal you. There comes a point where it is just not my problem.

I will keep the tank up and try to keep the rest of the group, but we CAN all use our eyes and notice what is going on at this point. Once those tank-mobs come down, target your party tank and go to the one they do. Meh. If you don't... kinda your problem at that point. My aoe-heal range is what it is. Hope the co-healer has got'cha, mate.
