Why do should the people that treat other people poorly and badly ever even have one corner in Eorzea? That doesn't make sense at all.
Elite players do not have the mean, cruel, exclusionary or treat the newbies with contempt. Those players are NOT elitist. Those player do get their hard challenging content. They always get a new one. The final coil will replace the second coil. And if the put in the effort to recruit build up a static, they earned the right to get access to those before the casual players, newer, or newbie players, but no one should have the right to exclude other players from T5, T9, or T13 or whatever content forever.
Nobody is asking for the "I WIN" button. That is what you call a strawman made up by the OP.

SE has good business sense about this. And it absolutely make sense. They have timing and pacing they want to set and maintain to move the story along, and no one is being hurt by doing this. The scripted fights are no harder than figuring out the timing and adjust for the bit of RNG in the script. It doesn't matter if it is T9 or ifrit story mode. The hard part recruiting and organizing people to commit to figuring it out. I was recently pugging T7, and we got Melusine down to 35% and this was after multiple PFs and multiple runs with different people whether I kited with my SMN or someone else with their bard. In contrast with my static, putting in a couple of hours for 2 nights in a row we got the clear on T7 with one new member needing to clear. But there is no good reason, once newer hard content replaces the old that SE should prevent 99% of the playerbase from getting clears old stuff because they cannot get a static. SE making older stuff more accessible is both sane and good business sense. And still we need to help new people in the FC get T5 clears and even that likely has not exceeded 25% of the player base.
For the TL;DR people.
What elite players earn is the bragging right earlier than everyone else and rightly so. What elitist should NEVER get is to exclude the rest of the player base indefinitely (a.k.a forever).
