Everyone saying "Nexon is doing bad business" and "omg Nexon so bad company". Try to remember this. Nexon is providing you with FREE, CONTENT. I repeat.
The game itself is not a business, i'ts mainly about how much time do you spend on the game that determines your progress.
And if you want to direct yourselves to "BUT THE CASSHOP BLUBLUBLUH I PAID BIHG MONIS FOR TIS GAEM"
It's entirely optional, none of it hinders your gameplay but it mainly consists of "i want to spend less time doing the things i can do for free so i will pay for it". You wanted to pay for something witihin their free product and so you did, nobody forced you.
My point being stop crying like goddamn children and appreciate that EVEN THOUGH the product is ENTIRELY FREE, Nexon is working nonstop in trying to fix the issue and decides constantly that instead of giving you a faulty product they rather take the hit from all the little kiddies crying over extended maintenance than actually letting their FREE PRODUCT be faulty.
