People didn't understand this before and they still aren't understanding it now.If they can afford to give us this many slots for KI's, why can't they afford to replace 50 of these slots for regular inventory slots?
Hell.. If KI's are so important, just let them overflow into my main inventory if I somehow manage to hit 50+ KI's...
It's not that you have that many "slots" for key items taking up memory space. You aren't "losing" inventory space because of key items. It's just that it's using the same display as your inventory to show them so it makes you think you are.
