Blizzard can keep trying, but the rest of us aren't leaving.
For not the first, not the second, but the THIRD time Blizzard is allowing (and arguably, by making it free and faction neutral, encouraging) Alliance to transfer off of the already imbalanced server of Skeram. But they've already beat our faction into the ground with these transfers. All of us who would have left, have left. The rest of us are here to stay, and we don't give a fuck how bad the imbalance gets.
I've been waiting for part 2, and so has every other alliance I've spoken to. Before guilds were fleeing, and now those that remain are forming coalitions. Before world chat was full of people debating whether to transfer, but now its full of people excited to camp horde. The auction house may be dead, and lfg too, but I don't think they'll be any problem grouping up for world PvP.
While the try hard min maxers who rolled horde to rank sit around waiting desperately for and fighting over the few alliance left on the PvE server they helped to create, we'll be farming honor freely. The horde on this server have behaved like utter pieces of shit for the last two months, and now its time for them to face the music.
