What I've brought from reading several threads and a little on the web, is that the game had a (working, proper, existing, etc) Queue system that was removed at some point between one of the Betas and the Final Relase.

The current queues (as happen now) seem to be capped at certain numbers, so any queuer above that number gets "Full world sorry".

But some players on other worlds seem to be able to get on 400+ queues whe nthe max I've seen with Valefor is 30. There is obviously a problem at how the queue works now. It seems the queue is calculated based on (not sure which?) number of players online.

The announced maintenance for Sept4th(00:00 GMT) is key, but the extra day of waiting for it isn't healthy...
