In one of the dev vlogs it says that all mechs are going to cost the same amount of acoins to upgrade despite the energy capacity. Plarium says that all the costs are going to be as expensive as 24 energy mechs but with acoins already being extremly hard to get, all the mechs should be the price of 32 energy mechs. Same thing should be with weapons that everything should cost the same as a 10 energy weopon.
