Ahh, I see. I read that as (play other games until there aren't queue's). Sorry for the misunderstanding.
Recruit a friend should bypass these restrictions. Friends ought to be able to play together.
I'm glad I got my alt to Gilgamesh (or rather on Aether) during the free transfer period, before the Shadowbringers rush.
If they are not shown as congested the servers will/can accept new characters. Best time to try this is on a server early morning like 6AM EST. Character creation is also blocked when too many people are logged in and will free up when they go to sleep and leave the server.
I don't know if this SE's doing. Maybe people on congested worlds are world visiting standard worlds, causing them to be temporarily locked.
They want new players to go to Crystal thats why. Even though many people moved off crystal when the server move was happening.
Good luck... I've had servers refuse to let me create an alt but they'll free up just be persistent.
Xpac appears to be having a big rush of new people. I think there is also a possibility they'll add new servers given what appears to be a red flag for new people and that certainly will affect their bottom line. They've just recently added two new servers in the EU I believe and it's very possible we may see more additions to other data centers as well.

Jeez! If its this congested then that kind of proves that NA needs more servers! At this pace maybe even a whole new data center of worlds....
Half of Crystal too is already locked to creation... What do they think will happen @ launch!!??
