In the short run, we are addressing the rate at which players can participate in war. There is a dev blog in progress that will touch upon this and more which will be posted in the coming weeks. The main goal of these changes is to prevent a very small group of players from determining the outcome of many wars, but it will help spread participation a bit
In the long run, now that wars are instanced, we have the ability to do instanced wars that are not related to the territory game. This means we could build a “casual war” sort of like OPR, where players sign up to play war and once sufficient people have signed up, it kicks off. There is quite a bit of work we still need to do before we can even start on this (like how do we deal with defender advantage or how we handle fort setup). So this is a long ways away, but its something we are considering for the future.
