Because I have decided to quit and walk away from the game, which also includes me not caring about or researching the classes anymore.
It was a fun run, but I've found that I far prefer the early stages of MMO's (ie. leveling up / learning / exploration) than end-game time sinks. And for whatever reason, the game just wasn't fun for me anymore so I have moved on.
Good luck everyone and I hope one day Shamans rise to power once again, maybe I'll be back in a year or so, maybe not.
