Most people in our community is using different types of troops while attacking other villages.
After spending those troops and spells you have to manualy create same army like previous one and that becomes really annoying after some time.
By adding this Retrain button we will be able to retrain same army and spells like in previous attack
without typing it manualy and that army should be equally distributed at barracks for faster overall spawning of troops.
Sorry for my bad English :p
