They are providing exactly the service they agreed to provide you as per the tos you should really read it. Being in que exactly matches the server requirements. Same with the transfer it only sold you the movement to the realm nothing more.
You can transfer with mail.
There is a thread in the support fourms to transfer with mail where the gms remove the mail for you to transfer really do people not look at the support fourm when they have issues that need you no support.
They will not make a 2nd realm the stated goal is to get people of those realms and not let them get to that size again allowing transfers back goes adverse to that and in fact is why the realm is locked and as they said is likly to remain so.
The real solution is to transfers. That is the real solution as much as you don’t like it. This is comming from someone on faer and no exactly how it is.
Also if your guild had to cancel raid due to the ques the issue is your raiders not the ques. They are nothing new and people have been dealing with them for awhile now. People have known they would need to remote log and stay online raid day to be able to play which is why everyone in my guild has been on since noon like many other guilds. If your guild dint have the foresight to do that ya transfers are what you should be doing as it’s not going to get better and if they can’t learn after months how to deal with the que they never will. So your going to keep canceling raids.
