Current State of End-Game Contents - A Blog Post from A Japanese Player

Never said there wasn't good people. Yet I am taking into consideration that those people that aren't progressing is in no way fair to expect for them to stick around 3-6 months just so that they can progress and then be blocked again from content in a 3-6 month period and constantly repeating itself and potentially getting worse, which it kind of has.

Isn't that time period the same for all tiers players?

Those on COIL2 have to wait 6 months until the next turns are released.
Those on COIL1 have to wait 6 months until COIL2 is made easier.
And so on.
