A game that rewards assets that are valueless is a traditional game, not an asset based one. Whether the assets are valueless because they are not tradeable, or they are valueless because they are vastly oversupplied vs what the market demands makes no difference. They are still valueless.
Certainly, the bots will stop playing Splinterlands when the rewards are valueless.
But if the Splinterlands team wants to have an assets based game without the bots, they are going to need an approach that is different from "make the rewards valueless." That's what the bots do by oversupplying the market! Is there a difference between becoming a traditional game because bots sucked all the value out of the rewards and becoming a traditional game because no tradable rewards are awarded?
I don't care much about botting. But I do care about farming--just getting rewards to get the rewards and sell them. If a bot wants to roll its rewards back into the game and play champion league, so be it. If a bronze league human wants to just keep selling off reward cards and not advance in the game, that's the botting problem. At a smaller scale, yes, but the same problem.
Farming needs to be addressed, yes. But addressing farming by making the rewards valueless just brings the negative consequences of farming down on us all in one fell swoop. Farmers might actually be better, they do it more gradually, at least.
I don't know. It's a problem, but I can't shake the feeling that you address it on the front end (the farming behavior as it is happening) or you won't be able to address it at all without just saying, this is a traditional game, nothing to earn here. Which I think is fine, too. Just own up to it.
Just because Reward cards become Soul Bound it doesn't mean they are valueless. It only means they can't be individually traded. They still have play-ability and can be burned for DEC when maxed. Plus they add to collection power. Bots won't stop playing, there is still SPS and Booster Packs in the daily rewards. They can build decks of MAX reward cards and then sell the full account. This potentially stops bots/farmers/general players from earning rewards for the purpose of dumping on market.
