Set Favorite Target

My idea was to add the ability to set the favorite target for troops. There could be a button, or something similar, next to the box that says the favorite target in the troop description. It could be changed or set for the troops either in the barracks, before they get trained,by clicking on the "I" in the corner, and then clicking on the button to set the favorite target. Adding this feature would add a whole new layer of strategy to battling in Clash of Clans. Now, attackers would have to train specific troops for specific buildings, or just leave it at "Any" to let them attack normally. Then, defenders would have to prepare their bases in a way that would try to thwart this attacking strategy. For example, the defender would want to set it up so that if an attacker were to have trained one group of barbarians that will attack resources, they would have enough defenses to stop it, but still have sufficient walls present to stop barbarians set to attack defenses. Although it may remove a small strategy that takes advantage of troop AI, the amount of strategy and depth taken away by removing that would be largely overlapped by the amount of strategy and depth added by giving troops customizable favorite targets. For example, with unsettable favorite targets, even though a last group of troops could easily take out a last defense, they go towards a useless building, and get taken out trying to gain a few more percentages, and so the player loses the attack. With settable favorite targets, the troops would go to the last defense if they were set with defenses as their favorite targets, and the player could win. Even though this may seem to be giving an unfair advantage, as the troops aren't just picking the closest targets, the defender would know this, and set the base to protect from this, by adding more walls to an area, or condensing defenses. Also, not all the troops need to be given the option. If some were to be excluded,something could be added to the description. For example, if goblins couldn't or shouldn't be changed, it could say at the bottom of the description something like, "The deep-rooted love for loot among the goblins makes it impossible to make them go after anything else until all the loot is taken." Or the balloon, something like; "These skeletons gain so much joy from destroying defenses, that they are determined to destroy them all first." If it still seems too over powered, it could be an option exclusively to the heroes. (As of now,the barbarian king and archer queen.) Now, just the heroes would get a button for setting a favorite target. This would still add strategy and depth because then, people would actually put a lot of thought into what they will do with them in an attack, not just say something like, "Eh, I'll just put the barbarian king/archer queen here, and see what happens." I have attached an image of what I think it could look like to this post/thread. (You can click on it to enlarge it.)

Nope nope nope... An army of PEKKAs marching towards defenses with jump/rage, all prioritizing said defences? I think not. Sorry.

No because then dragons will accually go for the TH instead of going around it all the time.

Another No. This has the potential to be incredibly game breaking. Learn to use the AI that's in place, and stop asking for an "EASY" button
