Better upgrades for troops

II play this game a lot and its fun but it would be nice if there was a little more variety I know there is normal/dark troops but I think it would be cool to have upgrade options for troops like say you have a lvl 1 barbarian and you are about to upgrade him but you had a choice make him Dual wield = slightly higher damage or fleet footed = slightly faster speed. And yes I know these stats already increase but If you were to choose dual wield instead of attack only raising by say 5 it would be 8 also would change the troops look it also wouldn't have to be stat choices maybe you upgrade an archer to attack defenses first or go for loot but the troops would retain their own specific bonuses like goblin's and wall breakers
