Thank you for your thoughts, Xor saw this and he said some of it would take a long time to implement into the game. So it could possibly happen? Not sure yet, we'll just have to wait and see .

Thus ruining shield code shops.

How is this a problem? This is an excellent idea, as it would get rid of things like people asking me where to get my astronaut helmet every five seconds and those who annoy others for codes. The scamming code shops would be decreased. It's not like code shops were amazing anyway, as the money gained is random and usually low, along with the codes obtained being mediocre. Again, congratulations for coming up with this great idea! Rep for you!  

It may be a while for this to be implemented into the game, as it would seem very difficult to make happen. It would definitely pay off in the end though! I would like to see this in the News soon! It would be a great update I think.
