No, when Ramuh is released, it won't prevent the i90 players from doing that fight. However, it may encourage those who do coil to stick with other coil players by only running in 101+ PF groups. And i'm not sure it's good to encourage players to segregate themselves from the rest of the population all the time. And it's certainly less ideal if you're in the situation where you're judged to be not good enough to run with a party finder group, purely because you choose not to do coil.
I mean it's not like coil players can't do this already. They can just choose to only run with their static or FC members if they choose to. If they're really determined to run with coil only players, they can just check the gear of whoever joins. In 2.1, if you were in coil you probably had at least 1 piece of allagan gear, same would be true for high allagan in 2.2. But those ways require you to be a little more proactive in segregating yourself from playing with others. But when it's so easy to just put up a PF with 101+, you may see more people doing it.
You do understand the differences between a video game where you pay for entertainment, college where you go to learn, and a job where you work and somebody pays you ... right?
