Why casual players don't 'just leave'

[Antharaes]

Im a raider and i've already been unsubbed for 4 months since DT release

Are you sure ? Because you need to be subbed to comment on the forums. After you unsub, you have 2 weeks to reply, after that you can no longer reply on any topic.
But I guess, since you're not a "casual" you have extended privileges.
