I believe that an auction would become a very important part of a RAID game: Shadow Legends. It often happens that when you kill bosses, an unnecessary item drops out. I understand that this is an accident. But when 6 identical objects fall out each with the same rarity and parameters, this is not very convenient and annoying. And most importantly - valuable things and it is a pity to sell them for such a small amount. I believe that the auction would solve this problem. That is, I have some thing in abundance, which is needed by another player. And instead of knocking out one item for 5-6 days, it would be possible to take and buy this item from another player for the price that he himself appoints. 

This will also solve the problem of routine in this game, on the 10th day of the game I really want to quit it, because the stage of standing is coming. Stronger or necessary things do not fall out, very often people leave because of this. The gameplay turns into "pressing one button."

I really hope that you will understand me, and I will see the answer to my idea, I like your game and I want to continue playing it!
