what is the most important defense/troops which will increase your ranking in clan war?
I believe inferno is the most important defense which increase your rank. If you have lvl 3 inferno with other average defenses (lvl8/9 cannon, AT etc), you will be in top of a maxed TH9 in ranking.
Next to inferno, I would say xbow. After xbow might be hidden tesla. I don't know. Any ideas?
But I am damn sure heroes and walls are not a big criteria in ranking. A poor defense war base with lvl 10+ walls and lvl 30+ heroes will be lower than a maxed defense war base with lower lvl walls and heroes.
P.S: This might be related to clan war, but I personally believe, this is just a general information of the weightage of our troops and defense. So posted it under general. Feel free to move this anytime.
