I'm a bit concerned where this is going.
I can understand server transfers being an optional service outside the game but changing looks and now item storage... I've played enough f2p mmos to see the bad direction because those 2 items are the top sellers in a cash-shop!

If it really comes to the point where we can buy additional inventory space, I can see the game losing players and eventually go f2p, regardless of what Yoshida said or promised...
