Well, the thing about that is ((keep in mind I haven't played this game since mid last year)) it was shocking to try to login to the red server and meet a queue, then swap to the blue server, log in immediately, and have all my progress wiped. If this game actually was concerned about queues and server loads they *could* offer an item that many many mmos offer via cash transaction called a "server transfer" that was everyone doesn't have to flood into the red server and wait 40 minutes to play if they don't want to. unless this is all some scheme to sell premium membership with the promise of priority queues (if this is even being offered).
so there are two options now stated to help the servers out a tad for the players: consistent servers, or a simple transfer of character between said servers
And this, "economical reasons", this games economy is brokenly pricey by design if you haven't noticed. moving past nothing being "impossible" online I would like to point to one of the most horrid examples of what a broken economy in an mmo actually looks like, Maplestory, and yet that game offers server transfers and is quite clear that they want to keep the individual server economies in tact, that meaning they limit the money you can bring and the items you can take with you.
