Yeah, gold pass is only 1000g, and the normal is usually somewhere between 1700~2000g. And you can only use it once, and only if you've just brought a new copy of the game.

As for it being cheaper, it's kind of debatable. Normal WP is only 400g a use if you get all 5 uses out of it, but like, when was the last time anyone managed to do that on a regular basis?
