Tools they could add besides DPS meters... (For endgame)

I love how in these discussions it's never okay to expect basic competency but completely fine to put additional pressure on the rest of the party.
If someone is barely performing at the required level, then happens to "just not play well" and drop even lower, requiring the rest of the party to make up for it that's completely fine, world didn't end, so what, don't be elitist and mention it.
If someone had to play at a much higher level to make up for the above mentioned, they better keep quiet and don't they dare feel frustrated by it. Damn elitist. Just feel blessed that you had the opportunity to carry others. Give yourself a silent pat on the back but keep your head down.

I sense a certain level of sarcasm with this post.

People have largely had an overinflated sense of competency requirements for the fight they're completing, so yes, that is not ok. If someone is not performing, or barely performing at the minimum requirement that the duty expects then that is a different matter entirely. Equally, people seem to be under the impression that someone playing subpar puts other players where they're in a position that they can show indecent behavior in reaction to the matter- Is silently kicking a player, leaving the party, and/or linking a discord resource for people to look at really that challenging for a lot of players before sliding out? Nobody likes the player that interjects with counterproductive nonsense with no other purpose than to disparage, as much as they do players failing to meet some arbitrary competencies.
