This suggestion could perhaps lead into a costume/NX Cover design contest in the future.
I do recall MapleStory having player created cosmetic items in-game.
I really want to see what's the problem of adding them in the CS for reward points on reboot, that's just make the game more engaging and the monster collection more useful since there's really not many things to buy with reward points in reboot and is a good excuse to go kill bosses beside mesos. Beside, is way easier to implement than changing the drop database.
Because adding things for "money" is not the way to solve issues. These boxes should drop in all servers from all mobs, and bypassing that by buying them is a really bad precedent for all future Nexon mess-ups.
You're right that the Rewards Point shop in Reboot is woefully lacking. But what it needs to have added is pets, pet skills, pet snack, and Water of Life - all Cash items that give a big gameplay advantage, which should not happen in Reboot. As things stand now, Reboot is pay2play, with pets and water of life being the "subscription fee".
Money, what money? the only way to gain reward points is participating in the game and completing game objectives, that's quite opposite at what pay to win is, not really sure you read my idea correctly but I'm just saying they should add them to the reward points cash shop, not anything else, same way you can buy cubes with reward points, is not different, you can even limit them to five per month the same way as cube are limited.
Actually, from what I've seen, it looks like they get paid by how many customers they handle, which makes them try to blow you off as quickly as possible.
Maybe you got one who was trying to be helpful, but due to not really knowing much, ended up copying knowledge base articles that were irrelevant.
Anyway, when a chat ends, you get to rate it and offer feedback. I don't know how often anyone reads this feedback, but it's the only way I know of to send any.
(Or you can go on reddit and post screenshots of your chat. Seems they enjoy deriding clueless GMs over there. And who knows, maybe one of the mythical Nexon staff who browse the subreddit will take note.)
