In Patch 1.4 we are addressing a few notable balance items, and we've also added Persistent Bodies and Decals! These options (accessible from the Graphics Options) allow you to control how long the bodies of the fallen warriors remain on the battlefield. We think you're going to enjoy it! Here is a full list of changes that will be in Patch 1.4:
