When you're using balloons and the last troop left alive is a balloon, the explosion they cause when they die should be included in the raid. Too many times I've had my last balloon die and as he crashes to the ground the battle ends. If the death explosion was given time I could've gotten the 50% or even taken out the town hall.
There should just be a second or two delay once the last troop is killed, just enough time for the balloon to explode on the ground because that's what we're supposed to get as a part of the elixer spent on balloons.
I DEMAND KAMIKAZE!
