Archer queen + Healer cheese
At TH10, I'm noticing that the meta I'm predominantly attacked by involves the 4~Healers + Archer queen combo. I think Supercell should reduce cumulative healing effects on Heros by healers for several reasons.
First of all, the AQ/Healer combo outranges air defenses. This is overpowered, especially considering that it takes about 3-4 point defenses + Xbow to outdamage 4 healers, and that's provided that she is being damaged without interruption. I find myself arranging my base in a way to stop this cheese mechanic but then this jeapordizes an arrangement that deals with all other types of "normal" attack.
At TH10 players should be exhibiting a deeper knowledge of attacking strategies, and I feel that the game is being cheapened by this cheese mechanic. Every time I open up my defense log I see 4 healers in the invading roster. Everyone does it because they are seeing that it is overpowered. If everyone was doing any other combo with such consistency, say everyone does Lavaloonion (which they don't anymore, cuz air sweepers/nerf), that would be a red flag to show that an overpowered mechanic is being exploited. Especially with SC's recent initiative to prompt players to try out different units what with the discount events. Why bother, everyone goes 4healers and AQ anyway. It irks me that someone can do 50% damage with this combo when it repels TH11 armies with grand wardens and maxed out units. Yet a TH9 can just put all of their dark elixir into the AQ upgrades, put 4 healers behind it and get 2 stars. It's a complete and utter joke.
Finally, why would supercell nerf healing spells on heroes but ignore healers themselves? If anything it's much more costly to use a healing spell on an archer queen because healing spell doesn't follow the queen and it has a limited duration, so it would be an inefficient use of a healing spell.
TL;DR = nerf Healer and archer queen combo
