This is just my opinion, but yba really changed a lot.
So, yba has changed from a fighting game to a trading game which is pretty lame. Like, btd is just a better version of kq, everyone knows it. But the tier list that updated recently moves frostbite btd back to frostbite base, this doesn't make any sense. I know it is a low value skin, but if this happens already, I guess the tier list and skins value in the future will be more terrible.
