A few people have been asking me if Ringus is cool for Clan Wars. To be honest, I have no idea as I've never used it. A few reports here have been positive though.
However, if I were a TH9 in CW I would use this...
I don't remember where I saw it first. I tweaked the layout to make the ring more robust. The weaker buildings are closer to the middle to try and prevent the 50%. The storages are used to protect those precious Air Defences. This was the only TH9 design I ever saw that really protects the Clan Castle. It is so hard to get the troops out of there as the ring of defences reside beyond its radius. In Clan Wars where the CC is reset on each attack it firmly holds its position as your most important defence.
This was the best trophy winning base I used at TH9, and trust me I tried
a lot. I'm still adamant that you need a ring base at TH9. The trick is making one that stands up to as many compositions as possible.
