You ask got best build but not SH? Well SH is the best for EE wars at the moment. Towered spies maybe? Massively towered attacks? Attacks with 100s of millions bfa? You ask for the best? SH is the best.
Sorry for a noob question, but I have zero experience with wars on here but would like to start doing them. An sh is all completely stables? The Teir 1 building? Even on the highlands and hoarfrost?
Lvl 1 sos all over, but a lot of things has changed recently. Nobody knows for sure what builds are gonna be the best.. but for war, you will always want towers for static defense. A hell lot of bfa as well, since bfe isn't static anymore, but that takes time. So Unless you're a sh, you need towers for war. What kinda build you want is your own choice.. hybrid, spy build, attack build, heavy spy or heavy attack hybrid.. depends on what you want, really
