You're right.
I think that higher gas price was a bad idea lol. It nearly killed the game, if it hasn't already. That, and the quick turnarounds for breeding. The system kinda lends itself to the deflation of rare traits prices.
Although, I do wonder if they did that due to predictions of the rise of ETH's value.
I would like to see the ETH network find a way to handle Cryptokitties and still be cheap.
