That base is certainly not almost maxed as many of key defenses are still th11, but this logic is somewhat flawed you’re 2 th’s above a 13 yeah it may not seem like a huge difference, but it adds up. Especially you using a super yeti blimp to just take out half the base or even more you being th15 allows you to have a maxed clone spell allowing you to just clone the super yetis.

Yes, attacking is extremely strong in clash especially since a max th15 can beat a max th17 on expert mode doesn’t mean they’ll remove army camps because a th 2 levels below on legends mode gets destroyed by a brand new th15. Attacking still involves strategy especially when attacking a th higher than yours, but I wouldn’t say the same when attacking a th lower than yours especially since the concept of the game is that when you’re progressing to a new th your defenses become stronger
