Elilir and Gold Donations
This doesn't have anything to do with new troops or spells but I know im not alone when I say that we should be able to donate Gold and Exilir in the game. I have many friends in the game that are filthy rich with at least one of these resources in which they have nothing to spend it all on. And there's other people that need some more gold/Exilir to prepare for a clan war or something. If clanmates could donate gold and exilir, it would make this game perfect. I will be very glad to see this in the next Clash of Clans update.
