Make gemming for troop request equal to barracks.
Ever noticed you would have to use more gems for a troop request then the same 10 minutes for troops to be trained in the barracks? 10 minutes of troops to be gemmed and DONE would be about 3-4 gems in the barracks. But 10 minutes into a troop request and u gem to request again you would use MORE gems than the same 10 minutes used in the barracks. This post is aimed more at the people complaining over my idea about a retreat option for Heroes. If you think Supercell would lose money by my idea think again because Supercell can set the number of gems for x amount of minutes and I just proved my point thanks!
