you really dont need to advertise your leave

[Isala]

There should be zero.
You want to quit, quit. There's no reason to start a thread on the forums.

You couldn't be more wrong. The chance for someone to see other people being frustrated to the point of quitting, and go "You know what. I feel the same way." and quit, is worth any amount of people going "This isn't an airport, you don't need to announce your departure."

They're angry to the point of leaving a game they love, I say let them shout it to the heavens for the people who might be on the fence. Sure, it still probably won't make the game better, because SE couldn't give a rat's ass about the community. But it'll still take money out of SE's pockets, one player at a time.
