they did say that. the ticket says it expires. they said the premium ticket was available in the cash shop. all the information was provided, you just didn't read it.
Too much information. Go to the damn NPC, it still lists in full about Mr. Yoo's quest. Unlike you, it's my first time there, and considering they left other quests there
(see this link) I didn't think they'd remove one that was both listed and a required way to enter. Of course, the rest of the aforementioned link says against it, but that is all after checking. You can not deny that it is misleading. A quest can range from a cheap 1k EXP to something enabling, and I didn't think they'd disable something that's already listed ingame. No one outright told me.
Are you getting me? Or do you still think I'm unjustified?
