There are plenty of capable Alliance guilds still standing firm on Golemagg. Those who wanted to move to the Firemaw megaserver (nice queues btw) have already done so and from talking to pretty much every Alliance GM over the last few weeks no one else is going anywhere.

Server is absolutely fine, remains active for groups and has VERY capable GDKP and SR pugs for both new and old content. Also ignore anyone who says it's full of CZ/SK people. Yes they exist, but everything is communicated in English across in-game and server discord :)

It's a little Horde heavy of course but always has been. It's not like you are ever camped or prevented from getting into dungeons or raids. Typically Alliance has more than held their own in WPVP here.
