All I want is a meter that shows grey to green symbols next to players names that is exactly like the aggro meter. Obviously SE has heavily designed this game to have DPS checks. They can set the DPS check at the minimum value needed for a fight. It's too easy for DPS to get a free ride there's no reason why they can't put in the effort minimal that is required for most content.
I know there's the necro'ed 2014 thread but this isn't about parsers or anything like that. Tanks and Healers have visible indicators that make you understand whether you're doing your job correctly. There is no reason in this game we can't have a DPS meter. It's extremely to see if a Tank or Healer fails but it's almost impossible to know who's not trying in a group of 4 DPS. I'm so sick of having to wipe to stuff like Bismark over and over because people aren't able to kill adds fast enough.
