What's the matter, Ghaz? Bites slowing down over on the official WoW forums?
Nobody who's passionate about vanilla is intimidated by the hydra losing another head. Every server dies. You read that bit by the Nost devs about making their code public after Elysium finishes capitalizing on the first dibs/gets pounded into the mulch by legal might? It seems common practice to start copy pasting character databases, too. Elysium got that. Elysium's successor will get the same treatment. There isn't much Blizzard can do to stop server "reincarnation".
You're looking at an endless game of legal whack-a-mole, with a nice little twist - the same mole comes up out of a different hole, good as new. It can only be stopped by people losing interest in vanilla, which is something that hasn't even peaked yet.
Now imagine what it's going to be like when this community gets used to this sort of bend-like-the-willow legal kung fu. When they get fast at it, and new servers start popping up in weeks instead of months. This beast can't be killed.
