As far as walls of text go, this isn't that bad...it's just not an interesting read.

Most of what the OP is complaining about is stuff we've heard a million times already (new content is ruining the game, all that stuff I worked for is meaningless, blah blah etc.), and I don't know why he's posting his farewell here. If you want to leave, say goodbye to your friends you play the game with and cancel your account. You don't have to publicize your departure for people who've never played with you to see.

That said, sorry you don't have fun playing this great game anymore, and goodbye.
