I've had very few genuinely good runs compared to how many were completely awful or sub-par. During the recent Mog tome event I saw mechanics in Syrcus Tower that I hadn't seen since ARR because the DPS was so low. To this day people still mess up Labyrinth of the Ancients and I have to actually tell everyone to wait before pulling the Atomos fight. Then there's other times where some people (who aren't new to a duty) just fail basic mechanics over and over and we have to carry them through, and if you ask them what the deal is they're just like "lol watching Netflix". My favourite are DPS that pull enemies before I even get there as the tank.

It's not hard to be good enough at this game and also not be a total blight on the rest of the party or alliance, but most of the time people just don't put in the effort. They just want to win without any effort, and get extremely rude and offensive if you ask them to just play normally. I guess I see it more than most.
