I feel like the nay sayers are thinking that the gate will be some incredibly difficult test that will greatly shrink the viable population of players while the type of gate that most people are thinking of would be something more around the level of simply clearing the Stone Sky Sea for the fight. It is something you should be able to do if you are even thinking of attempting a fight and shouldn't be difficult at all.

For those saying to just make a static, not everyone has a stable schedule and thus are forced to use party finder. They shouldn't have to be forced to deal with people who don't even know their class rotations, such as ice mages. Is it really too much to ask for people that know the basics of their class?

This shouldn't be that hard of a content gate to clear and shouldn't shrink the population at all.
