Several members of my clan have been asking for "Defensive Troops". Which got me thinking what are some good defensive troops that are readily available at the Barracks? Troops that Most members will have access to. So lets try to cap this at nothing better than healers.
So of barbarians, archers, goblins, giants, wall breakers, balloons, wizards and healers which are the very best at defense? By best I mean likely to save you the most money. Whether they kill the enemy before they can do damage or draw enemy fire works. Longevity of troops is also an important element to consider.
I am aware that what the enemy attacks you with will have some impact on this, so let's limit this to which troops are best most of the time.
