Let's touch again the sensitive subject of trading. I know, is hard to approach this subject but i want to give it a try.

When is coming to trade in this game the biggest issue we encounter is the second account abuse. But that thing should be easily prevented by introduction of some rules:

in order to trade players must to reach a certain level(let's say level 100);

players who want to trade need to be in the same group;

selling of power items should not be allowed only ninja fragments;

and minimum 50k battle power.

Selling/Buying

Buying should be allowed for all players that meet the above requirements. Selling on the other hand should be allowed only for players that again meet some requirement:

a certain number of convoys made in a period of time(i will explain what i want to say with this);

possession of a merchant license that can be obtained doing convoys or bought in the game shop with either coupons or ingots(but not a crazy sum, let's say 1000 coupons or ingots);

and the most important thing one player should not sell fragments with a higher value than the two times the sum spend on the merchant license (1000 coupons spend on license not more that 2000 coupons made in shop). That is why the chance of getting a license doing convoys should be a low one.

Shoping period

Of course the sale must be tied to another event. In my opinion the Season System is the best choice. And it should take place in the last week of the season. And everyone who wants to sell must obtain their license in the first two months of the season, and those convoys that i was talking about should be made in those two months to.

That is my idea and i strongly believe that this thing is want this game really need in order to make a huge improvement.
