I would generally agree,
in a war raid cost should not matter. But one of the other CHIEF complaints about mass drags in war is that you lose resources even though you win.
My method addresses these two complaints about mass dragons:
- mass dragons in war raid cost more than you gain. (not if you use other troops with it and utilize the right spells) I break even or gain a bit of elixir with my method.
- mass dragons in war are not a "strategy" they are a spam. (a large group of dragons placed carefully, WITH other troops is not a spam. )
Does that mean than in a war raid I wont go all dragons for fun and burn a TH9 to the ground? Aw heck, I love doing that. And I can do it with ten lvl 1 dragons, no other troops and 2-3 heal spells. BUT I prefer to put some thought into how I attack. I still prefer heal spell to rage spell. (but then, maybe because I am a woman I prefer to see my dragons survive instead of go berserk and die before the mission is completed?)
I speak from my experience within my TH abilities. MANY of the people who use mass dragon tactics are TH7, or early TH8... JUST like me. They cant afford to use Hogs in every raid. They might not even have hogs yet. Heck a mid lvl TH7 might not even have rage yet. Heal spell is effective.
The OP is a TH8. He/she may not have upgraded the rage spells totally yet, may not have the ability to take more than 200 troops, and may not have upgraded hogs enough to make a difference against big bombs yet. My experience and input is relevant in this discussion.
Dragons are
not easy to control. They attack the nearest target, which means that the group WILL split up, spread out and be easier for AD/WT/AT and air bombs to pick off. Yes, hogs to one side will help, but DE is precious at TH7/8. Hogs are not always the best option... Even in a war.
