i brought this up in cata - since some guilds are having a hard time recruiting one option is to combine with another similar guild and have people compete for raid spots.
i doubt many people are transfering to andorhal except those coming to simple math. if there is another competent and competitive guild then they'll be able to get people to come as well.
i still think that merging a low-pop and low-progression server into andorhal is one of the best ways to kill two birds with one stone. people on a *horrible* server will have an opportunity to raid and andorhal would get a much-needed boost in population.
LOL, all I know is when I tried to get into SM, and 2 people in there that played alliance before didnt like me, I was turned down to even just be in the guild. Basically there is NO ANDORHAL, there is only SM on this server, and if your not in the guild there is no point in staying on Andorhal. Any other option is futile, and I wouldn't recommend it. We tried several times to build up alliance with NPFS, lasted about 2 months into Mist. Then we tried Death Merchants(which was actually a 25man raid) which also failed. Then when one person tries to get into the only guild that is actually doing something, just to maybe have a chance in a off raid or alt raid, they are denied. Then you sit in the server forum and cry to help you revive the server LOL, the irony. Wasn't it you the same one that said, Andohal "We are doing just fine" when people started complainig about the server in Cata. Now you see that pretty soon it will basically just be SM raiding, and I am pretty sure the guild will eventually be in the position to find a home elsewhere so start looking. As for everyone else on Andorhal I suggest you transfer out to a high pop server, get your moneys worth. For Alliance I would recommend sargeras, horde would be illidan, and if you like pvp i would suggest Kil'Jaden, I have toons on 2/3 of these server and you can basically pug full clear TOTs on these servers. Before you transfer I would suggest to go into a website that tells you the ranks of the guilds and their progression, when you find something you like go to that one. DO NOT JUST GO TO ANY REALM, you might find yourself on another andorhal and have to spend more money to get out again. REMEMBER YOU STILL HAVE SOME TIME TO GET THE 50% OFF TRANSFERS. DO IT
Stop crying about the server if your not willing to help out, except for suggestion on what other guilds can do.
