As a personal query, I don't have any modding experience and I'm not very tech savvy, but if it's as simple as changing afew .xml files I'm up for having a stab at it. I simply prefer my battles to be rather drawn out, the tanks seem to die in three hits from another just doesn't seem to last long enough, for my personal taste that is. If anyone could help me out that'd be much appreciated, more so if you can do it for me. Thanks for taking the time to read this.
There will almost certainly be a mod for this post-release. However, it is currently impossible to do, as Uber have not released the server for modding - we can only mod things client-side.
