I can understand your sentiment, but the problem is when you're doing content thatrequires someone to have been a 60 for a long time and they are playing their class in a way that their performance significantly slows down their group. There are no alternate playstyles or nonsense about "playing how you want to." Each dps class only has one rotation and one way to play it correctly. You're profile says you're a 52 dragoon so I'll assume you know at least the basics of the Job, I was in Sohr Khai a few weeks back with a 60 drg (the dungeon requires an ilevel of 205, which means this person has to have been 60 for a while) and they only used three attacks. Heavy Thrust, True Thrust, and Impulse Drive. They did not use any jumps, did not use any combos, and did not use any cooldowns. When I called them out on it they said "I'm playing fine, no one ever complained before."
They legitimately believed this was a correct way to play and with their gear (mostly 220-230!) they should have been top DPS, instead they were below the healer who was only healing on the threat meter. I had to leave the group because we could not beat the dps check on the second boss. That is not an acceptable way to play. At that point the person should have been aware of even the most rudimentary basics of their class, they were honestly the worst dragoon I've ever seen and I told them as much before I left the group. I don't care if it's their 15 dollars a month, it's not worth more than the 45 dollars of the rest of the group.
