Character trade - SWITCH

Hello everyone, I want to suggest to add a character switch to trade options.

For example : I have character lvl 70 hunter and i want lvl 70 priest. So I will choose my character, add description ( like char selling ) and i will choose Fraction, Classes, and LVL ( for example min. level 65+ ). Now people with character that passed all conditions can simply click - offer my char. Then Seller could choose from XX offers and thats it. At the end, just both players once again agree with trade and it will switch characters.

I just type a basic idea, it dont have to be like this, just add options for character change. Now, people have to switch it trough COINS, and its realy dangerous for both players.

( Sorry for bad english, just want to add this idea )
