I live in a world where I realise that nerfing one class only drives its player-base to either quit the game or roll the new FotM, which then will be nerfed eventually only to continue the spiral into a game that has very few players left, because eventually the nerf bat has hit them all.
Seen it with pretty much every promising MMO in the last few years (WAR, RIFT, Aion and the pletora of other non-factor MMOs).
