I found this card linking system unfair. I spent a few months without accessing the game and when I returned, unlinking some of my cards was costing more than 300,000 DEC. Now I have unusable cards, considering that I have others of the same type with a higher level, and there is nothing to be done. I can't rent them, I can't sell them. What is the logic of an NFT game if we can't manipulate our items in the way we see fit? Obviously, this strategy only benefits the game's whales. We, players with few resources, will not be able to pay this increasing fee. Because of this, we will stagnate because we don't have enough resources to rent or buy other cards on the market.
Free up these linked cards for rent. It doesn't make sense to keep using useless resources. Don't deprive small players, we need a competitive game, not a pay-to-win game.
