I'm pretty much in agreement with Vyndree on transferring servers. I wouldn't want to spend $250 to move all of my characters, nor would I want to re-level without R-A-F. That, and I have several "real life" friends on Burning Legion, I have the economics of the Auction House on the Burning Legion locked down, and my main characters are getting into raiding/progression guilds. Not to mention, I'm pretty much feared by the Alliance on the Burning Legion since I can 2-shot anyone (literally, yesterday the Alliance had to bring in a calvary of 12 guys to take me down). Multiboxing is fine for instancing, world pvp, and farming, but so many "end-game" encounters require coordination that can only be attained with either luck, or by single boxing. As I start to get into the end-game, and as my "real life" friends are getting into it, I would really miss the progression aspect of the game.
