Defensive barb king attacks dragons
I'd like to formally request for SuperCell to allow for defensive barb kings to attack dragons. The reason can be that the spread from dragon's breath requires them to get within range of the giant barb king's arm/sword to damage him.
As we all know, dragons are completely overpowered at TH7 and still mostly overpowered at TH8, and irrelevant in 3 star strategies past TH8, so we really just need to look at how this affects balancing at TH7 and TH8. At TH7, your typical three lightning 10 dragons 4 death loons yields an attack that has 8+ dragons surviving the attack even on a maxed TH7, which is completely obscene. Allowing the Barb king to attack dragons might make it slightly harder for TH7s to three star other TH7s, which would be a very welcome change.
At TH8, with the sweeper update, obviously its harder to three star, but level 3 dragons are still way too strong for an attack that relies on one type of troop and minimal skill. I don't see much of a downside to making mass dragons harder at TH8.
The reason the BK can't hit loons, minions, and hounds is because they drop projectiles which do not spread out and thus can attack the king from a safe distance.
If someone else has a better idea to help better balance mass dragon attacks, I'm all ears, but this slight tweak has essentially no downside.. Although I feel people will oppose it for no reason other than they hate change and want to pretend that TH7s aren't totally defenseless against competent dragon attacks.
The harpoon Tower is a great idea
I agree with the harpoon tower idea.
