Achievement or stat showing how many kills/structures a Barb King or Archer queen has

Hi Supercell,

Since the heroes are supposed to be immortal, is it possible to start keeping track of how my buildings or kills a Barb King or Arch Queen has? For your consideration.

Seems like a pointless idea sorry...

Well... If they keep track of how many builder huts you destroy, then I dont see why this would be more pointless that that.

It can be an added achievement , which results in gems for the players of course.

Heroes are immortal... but there is nothing currently tracking how much devastation they have wreaked.. which I think would add to the lore of them being royals and all.

I don't think it would detract from the game much but all its saying is how much people use there heroes, seems pointless to me sorry
