Unfair trading

I don't know what make the game think trading 1 120 ovr and 117 ovr for a 120 ovr with silver trait is a fair trade. It's like getting a 118 ovr but with 2 plus ovr, what do I even trade for? All the 120 ovr from the store right now have a golden trait and a silver trait, there's absolutely no reason to trade them for a fake 120 ovr card. Does the game really contempt players that bad?
