Sounds VERY crazy to me. 3 stars would be in high amounts and everyone would start getting dragooned - I know dragooned does not mean getting attacked with mass dragons but I'm using it solely for this post - and this game would be no fun.

At TH10, there are other strategies that are twice as effective and half the cost. That's all I was saying.
Dragons had their moment at TH7 and 8, but at TH10 they really are quite pointless. Obviously I don't agree with what the OP said, but I still don't prefer dragons all that much myself.
Use a heal spell or rage spell. That's what they do, heal and make your troops more powerful.
Air defences were practically made to stop dragons. That's what they are there for...
if if dragons only attacked air defences any base would be 3 starred.
