hi i have suggestion i think needs to be implemented.
a player market or auction house and i have 2 versions of this to suggest.
1st it would be handled just like trading chakra inside groups only, or 2nd it would be a server wide trade or even cross server wide.
okay on to how it would work, well since everyone has useless items in their inventory, even low level players who got one too many blue gear upgrading materials, or when you spend 25-30 tries a week trying to get that ONE elusive ninja tool and everyone else gets 4 of them. well what i propose is that in either case 1 or 2, you would set up items for trade and then either oasgames/narutoonline whatever determines each items value and it can only be sold for this amount or my prefered that players determine the price of items sold, and here is the kicker all sales will only be able to be sold for cupons/ingots (first deducting cupons), AND the house aka oasgames/narutoonline would charge 10% of all sales, this way not only is it a paying/premium feature but you the company also make money on each transaction, this would not only benefit high spending players who could clean up their inventories and at the same time earn cupons which they in turn would spend on other events, but would also benefit f2p players since they could earn extra cupons for their unwanted items or spend their hard earned ones, and then be able to buy items that higher lvl players have put up for sale for instance.
now i know what you are all thinking in either case this could be abused, like join our guild we will give you tons of power! or making alts to trade with your self, or just helping like one person in the guild get insanly strong to dominate rankings etc. however as i havent worked out all the details of this suggestion, but i am thinking that there could be a limit on how many items one player can sell and/or buy each day to prevent this, or a minimum character level or something like that.
this would not only eliviate the frustration of a lot of high lvl players with tons of unwanted stuff but also benefit all players and make the company money. hope you will add your suggestions or tweaks to this so we can get it implemented :)
