Part of what maplestory fun were the new jobs. Evans, Arans, KoC's, i don't see why they shouldn't be added. Anything else sucks. New classes will help bring in more people and keep people playing with new content. Please don't say "it's not part of the original ms." I, for one, think it is. It added more originality (if that even makes sense). There was nothing wrong with those jobs being added during the live server, it only added on to the gameplay, unlike other jobs like DB's which were just knock offs
Some people already find it difficult to deal with chaos scrolls, whitescrolls and dark scrolls because they weren't in the really old maple most people played. Imagine what those people would feel like if you added Aran and Evan
In my opinion we need to take baby steps. I think the new skills table will make enough changes for a while. If it goes well with the community, maybe later on we could discus about implanting KoC \ Aran in the game.
