Yeah, do what Blarvin says, transfer off to a US rank 10 or higher realm and be just as bad as you were when you were still on Kalecgos.
Transfering and merging won't fix your problems, playing the game well will. No one wants to go to realms with low pops because the players are never good. Realms get higher populations when there are guilds to attract them there. Kalecgos had it's moment when Cuties carried it to the top 30 ranks, but once they disbanded, it turned back into the same early LK realm. Same effect happened when Audacious left back in BC, everyone left because Audacious was a high ranking realm and people were attracted to Kalecgos to join it. Now, there's no one left to help you guys. The floaties are off, now you have to learn to swim. If you find 10 people with no lives on Kalecgos and get them to raid 4 days a week and get 10-15/16 Heroic, then your realm will flourish again.
Developers have already stated that merging servers is just a bandaid to the problem, not a permanent fix. If they crammed everyone on 50 realms the game would become tasteless. Many players on Kalecgos don't play on higher pop realms like Mal Ganis, Illidan, Sargeras, and Stormrage, they don't realize that you go from 100g gem prices to 20g gem prices and making gold is not nearly as easy. It's not all it's cracked up to be. Sure you could go to a medium pop server where everything is decent for a few months, but once the top guild leaves, everyone else wants to.
If you want a permanent fix you have to give !@#$ up. Do you want to make 100k gold a month of a bad server like Kalecgos? Or do you want to make 4k a month on a large server like Illidan or Sargeras where there's loads of pvp and pve? Either way, there's no guarantee you'll get better or enjoy the game more when you leave the server.
Just couldn't avoid taking a chance to pat yourself on the back and blast blarvin could you? Man you're one pathetic dude.
