My idea is that you can upgrade troops skills to make them better. Things like attack speed, movement speed, possibly changing prefered targets could be considered skills. You would upgrade a troops skills by gaining skill points, which are different than gold, elixer, and dark elixer. You can gain them from 3 staring opponents in regular attacking and wars, donating a certain number of troops, or upgrading defenses. This would motivate players to donate more and participate in wars. I appreciate any and all feedback as to how to make this idea better or if it should be put into action.
