Well the price of the game outside of the Origin Store is determined by the Store, so if it's a physical store's prices you are complaining about, then that isn't EA's fault.
You'll still make profit and honestly you'd probably make more money because people can actually buy those dlc's. I think $20 for your big dlc's and maybe do $5-$10 for your smaller ones. I remember when dlc's used to cost way less then this for any game with the same amount of stuff you put out. It's a successful game so dlc's are released, but then you charge us $40 for the the ones that are actually good and give a new play experience.
Why is everything ridiculously over priced? EA is just milking their franchises.
