Hi. 

I just  update my game(in xbox) and found upgrade price has reduced.

Some upgrade for charater was 8 to 5, and weapon was 4 to 2.

But why didn't refund previous upgrade cells?

This game has limited cell numbers which is totally 245.

But if you want upgrade or unlock all of yours needs around 308.

(224 for Charaters, 108 for weapons, 48 for bot)

I know all the players do not upgrade everything.

And that's why Dev placed limited numbers cells.

But if you do rebalancing the economics, should refunds used cells.

Unless cells are plenty enough to do upgrade everything.

Please tell me my calculation was wrong and Devs was right.
