I don't understand why people say Old maple was so much better

I don't understand the desire for "exclusive" content. Version exclusive content almost always completely conflicts with the design goals of the Korean developers. It causes balance issues, it causes glitches when they try to tie it into new content, and it's generally detrimental to the game. Yes, it does give you something extra to do, but I'd rather just see more content pumped out by KMS. I think sometimes people forget that KMS is its own game with its own share of players that "only get updates from KMS."

Well, balance issues matter very little in a game where there's no balance at all. Everything else, yeah. Not to mention most version exclusive stuff tends to get ignored, with the exception of JMS exclusive content (since Japanese people actually know how to make games).
