If what I am about to say is already possible with what we have please tell me.

Add different trench wall heights and sizes because the trench walls we have now are all to tall for any trench to trench warfare. For example, one height could be called jump height because you need to jump to fire out of the trench another could be called stand height where when you stand you can fire and when you crouch they can't hit you.

Also, please add flak air blast skybox effects and other effects for skybox war visuals.
