Not really, put it at a huge price and the system remains intact.
Please give us a way to concentrate on getting the Rare/ex brown chest item. The drop rates are far too low considering they are more usefull for side projects like skilling up or HELM activities.
Why would you do this to yourself? I always look at it like this commit an hour to a half hour to getting said drop, if it doesn't work out. Get into something else for a while, and come back later to try again. I notice with this style of play I normally get what I'm looking for within a couple of trips or more. And I don't lose 18 hour's of my life with nothing to show for it.
Maybe let us buy some of the Rare/Ex items with tabs. I mean I spent probably a good 16 hours farming Prouesse Ring over 3 days and still don't have it. I mean of course it would be completely unbalanced to not leave something up to chance but it's just an idea.
