With regards to communication, do you mean in the fight or communicating what runs are needed and forming parties for that? The LS could have a rule that you need to be able to use mumble or something if that's what you mean.

Ryu, in response to your message on FD forums (because I have a bad habit of reading a message, putting down my phone and then forgetting about it because the little notification icon is gone) you're welcome to advertise your LS it on our forums in the general discussion area, you should still have access to that. As an FC we've cleared everything but Ramuh and SCoB, but we just started up our static (Friendly United Coil Killers: Endgame Raiding Static ) so I personally wouldn't make use of this LS.
