A war is usually for some kind of material gain, like land or wealth.
The implementation of PVP on this server is basically flawed because you can't really do either of those very well - the faction points are far too high to let any faction take any land from an opponent without killing every member of a faction many times over.
If you blow up chests, then maybe you could loot the contents. Simply destroying a building though achieves nothing, other than petty vandalism.
So I wouldn't really call it total war. It's very easy to create an invincible fortress, and even easier to simply build underground, and if you do that, the whole war idea is moot.
