I suggest you to add Queue. Like in some other mmo (f.e. WoW). When the channel is full, we cannot join, but when queue will be added, we will be automatically put into queue and wait for the time when we could play. Also helpfull would be if there will be any information about queue (f.e. how many people are in queue "in front of us" even with aproximation)
