"Q10: Will you be able to form your own alliances and enter Crystal Tower?
A10: In patch 2.1 you will not be able to form your own alliance. You can enter with a party of eight."
Please SE pull your head out....
There are many LS/FC with 80-100+ members who are ready for some big content. I know we have been ready for a dynamis sized event since day 1 of 2.0.
If you cannot see the forest between the trees then maybe you should limit the LS/FC size to 8 players as your content is built around 8 players, your game does not foster anything for massive groups and their leaders other than a headache.
Please reconsider your mistake
