One man`s trash is another man`s treasure. At least if they put them in the mog station (I understand that they do that for something that comes from some other version or did cost money in the other version too) we do have the chance to get them. If its your taste or not does not really count for this imo. (Especially since we already have trash [imo] that is the yokai mount)
IMO the event items are far away from being cheap. Anything that is over one dollar for a simple wallpaper is too much, especially since Yoshida said that they dont want to earn money with that move (suddenly putting the event stuff in the mog station and not leaving them ingame) but give others a chance to own them..yet when you look at those prices..I mean those are items that are already ingame. Thus not something that was just created for cash shop.
That "argument" can be used to anything. You dont like Eureka? Just dont do it. You dont like content x just dont do it. Just because we have the option not do it/or buy it doesnt mean that we should be fine with that.
I can understand that it would be too much to give us that for free if the other version had to pay for it. But why exactly is it entitlement if someone wants to pay less? Its a digital item. And in the end are you entitled too if you buy something for less in real life? Do you go and say that you want to pay more because customer/country x had to pay more? I am quite sure that most wont. And thats about real existing items that may cost the shop money even after creating it.
