I briefly played this game when it came out years ago. I thought I would try the f2p and check it out again before buying any expansions. While I am downloading this, I was browsing through the forums and am a bit confused about something.

Even if I buy all of the expansions, I still will to buy additional things to unlock more zones and quests to unlock everything?? Isn't that what buying the expansions are for? Could someone explain this to me? I am a bit confused at the logic of this, if I am understanding this correctly.
