Have an option for friendly fire or make it easier to breed troops

Its really hard and annoying trying to maintain an army when your own archers are killing off your first line of defense... Although I'd also be happy with if it took less crystals to spawn in a bricktron knight. I imagine a system were a knight would cost 25 crystals, an archer costs 50 crystals, and a worker would cost the full 100.
