Hey guys!
So, I've been working on getting my defense up. Part of that has been working on walls while the other is working on defensive buildings. But what I want to ask is what's the best way to get everything upgraded? More specifically, what defenses should I upgrade together and when? For example, is it better to upgrade a single kind of defense at one time, such as all air defenses or wizard towers? Or is it better to pick a few different buildings such as an archer and wizard tower to upgrade at the same time?
The reason I ask this is because I am currently in the process of upgrading both my air defenses, but I am being raided by air units particularly often. I think it's because they are taking advantage of my air defenses being unavailable, but I wanted to get your guys opinion. Thanks.
