It appears Japanese players are in agreement.

If you want a decent comparison, Clan bonuses and ranking were expensive as hell in certain old korean grinder MMOs.

Hell yeah. 'Back then' expect a year's (or two) grind without cash shop item trading to roll around in a million of in-game currency.
But realize that in auction houses all the good stuff cost in the tens and hundreds(!) of millions.
So the poor stay poor & the rich get richer.

But that was 'back then'... =x

For stuff to cost so much this soon after a few months of release is just ridiculous.
If it were player set pricess, then inflation to millions makes sense but... set by game itself by default?

Well, that's one thing to ignore until a much later future.
