But still, isn't making upgrade plants on full price wouldn't be very frustating? Or how about having Upgrade Plants have options of cost, so if you have the required non-upgrade plant in the seed slot, it would costs half from the cost, so you can either choose the upgrade plant by itself but it costs full, or choosing the upgrade with the non-upgrade that costs half would be cool, so you have options.
