YEAH! YOU ARE RIGHT NOW IT IS VERY DIFFICULTY THAT IM RANK 1 AND I HAVE ONLY 1 TOKEN SINCE 1 YEAR AGO ITS VERY BAD SO WE NEED TO DO TRADE ALSO THE GAME WILL BE BECAME MORE POPULAR THATS WHY WE WANT TRADE.

A trading system would be easily abused, as it would allow people to transfer powerful items from different accounts into one main account, bypassing the need to spend money on tokens for item boxes to 'build up' an account. Because why do that when you can get whatever mythicals you need on your main account if you have an army of alternate accounts, all with mythicals?

Hope this clears things up for you
