Switch Dragons and PEKKAs in the barracks
It is extremely easy for a th7 to three star another th7: all that is required is 11 dragons, 3 lightning spells, and the skill required to tap an air defense.
Dragon attacks require no skill at th7, yet they can be used by any th7 to virtually guarantee a three star on any th7 base. EDIT 3: No one has disputed this or questioned this. Everyone accepts that dragons can be used to three-star any th7 base with minimal skill.
I see so many threads to nerf dragons and how OP dragons are, but I realized that the problem was not dragons, but dragons at th7. Thus, a solution needs to be implemented not to nerf dragons, but to nerf dragons at th7.
My proposal: make PEKKAs the 9th spot in the barracks, and dragons the 10th. Thus, dragons are unlocked at th8, and PEKKAs are unlocked at th7.
I propose that PEKKAs cannot be upgraded at town hall 7, to retain the balance so that th7s cannot be easily three starred no matter what the base. At th8, PEKKAs can be upgraded to level 3.
This will fix the problem of defense being worthless at th7, so dragon attacks can't be used to three-star anyone.
EDIT: Before you go and tell me to "build a better base", say that I'm "mad that other people can three-star me", etc., please notice my signature, where my TH level and player level are clearly displayed. I'm making this thread to help TH7s.
EDIT 2: For this to work the level 1 PEKKA would have to be nerfed to be in line with TH7s' defenses and lack of powerful teslas.
