I could start by saying all I ever face is townhall 7+ when I am only TH6, how am I supposed to even fend off a townhall 8 or 9?
But I find out its trophy based. Ok, there is a problem though, healers.
I have air defense, but its always dead first no matter where I place it then they place healers. They even started on the other end away from the air defense and it was dead before they got close. My well placed springs killed 13 of his 16 giants on their own, but my 2 archer towers, mortar and cannon that were left weren't able to kill a single unit after that.
How are you even supposed to do anything against that. Air mines are useless against anything but Balloons.
I dunno, my clan castle had high archers but he used a lightning potion.
I constantly get raided by either healers, or some townhall 9 that doesn't even bother with tactics, he just spams maxed out barbarians and wins.
Air bombs are also useful against minions.
And haha that's like saying balloons are OP, but all you gotta do is find some space in the middle of your base to fit your air defense in, also make sure every part of your base is covered by an archer tower to pick off at those air troops. Just mix your base around a lil bit and you'll find something that takes healers down.
Anyways, center your air defense if you want to counter those kind of attacks.
Upgrade point defense (e.g. Cannons and Archer Towers) so they can kill giants faster.
