Incentives for players who spend real money on the game

I think that this is not an unreasonable request. I spend a lot of real money on this game, buying decorations, additional diamonds, special offers, pretty much everything... It would be nice if Supercell gave players like myself an additional incentive to keep spending real money by offering one diamond for every dollar we spend, so if I spend say $15 of real money, I would get 15 additional diamonds for it. It would make a nice additional reward for people who like to support the game financially...

Your particular method of asking them to make diamonds cheaper will require them to track currency exchange rates in every country that has a paying customer.

A real incentive would be to give paying customers something the f2p players cannot get (deco or status symbol), though at the moment they seem to be deliberately avoiding that.

This could apply to any currency, for every 1 coin spent on in-game purchases, the player receives 1 extra diamond regardless of what currency they use. Money is money afterall 🙄.
