War was popular back in the day because it was one of few servers with a gun plugin. Nowadays every server has a gun plugin, including Mineplex and Hypixel. WarZ is a unique concept because there's not many servers that live up to the original Arma 2 mod. War used to be unique because it was COD in minecraft. Now it's not. There are dozens of other servers with the same thing, but what made war better than those servers is that it didn't use crackshot. The playerbase of Minecraft's online multiplayer scene has been declining for a while. Everyone who used to play here eventually moved on to somewhere else and their forum profiles are littered with posts asking them to come back. Just give it up, man. War didn't even have less than 30 players on individual servers back then. At this point you're better off just buying MW2 and playing that.
