I’m back for good. Balnazzar was my home server back in vanilla and TBC and I had regretfully transferred off during WOTLK as the population was getting smaller once blizzard had opened up server transfers. I was the servers first gladiator warlock and hopefully I’ll get to see some old faces/players if anyone still plays from that era 
Now that we have cross realm/faction/guilds/servers and warbands to offload goods to sell or transfer needed items from higher pop servers or join raids cross server, there’s no reason why we can’t come back.
Hopefully former Balnazzar players will consider transferring back if they had left like me now that quality of life has dramatically improved.
