The servers were essentially 95-99% of either faction, and they locked migration several times seemingly on random. A lot of people got stuck on servers that were nigh unplayable because of the other faction dominating everything.
It even included paid server transfers on some servers for some weird reason. I got hardlocked on 98% alliance server while playing a tauren resto druid. Their customer service told me to “level another character on a server of my choosing”. Leveled to 80 out of sheer spite and then quit when my game time ran out.
Truly one of the biggest disappointments in my entire life. I know it’s just a game, but I had looked forward to getting to redo wrath since they first announced classic in general, and they completely ruined it.
