SGG i can understand, that you will lose if there would be trading in this game, because people would trade the hotm which they want and had no need to summon.
But if you give us a hero market, where we can sell our heroes, it will be a win win.
People can sell their Christmas, Halloween heroes for 100k gems.
Event heroes und season 2 heroes like guin, or tarlak for 50k gems.
Hotms for 25k gems.
Tc 20 heroes for 2600gems each and so on.
People who wants to buy These heroes must buy gems. The guy who sold his hero will get the gems and can summon with these gems in the Future.
Everybody will be happy. The seller, the buyer und YOU SGG.
