Mythic item! Yay..... and it cost Koban, straight down the slope. I mean I get it, Koban is the ultimate currency and the major method the game earns money for the developer, but seriously? As if we don't have enough things to spend our not-so-abundant Koban on nowadays. What is Yemen even useful for when you hit around 400 before this patch? Pretty much nothing, we have more than enough of it for the needs, and now it has been further depreciated.
Again, it sadden me seeing another Koban only product on the shelf, but I don't have a strong opinion on it, as I shouldn't anyways. But please, give us a meaning of earning Yemen at least. Maybe by introducing other features that we can use Yemen for. For now, that thing remain a shinny, big yet useless number, and it seems like it is getting more and more useless.
