Tactisoft, if there is any statistics tracer, can we have a look at it?
If not, one could be made with all the replays. The following tracker would have all the wins, losses, and popularity of each equipment (and perhaps popular mech designs). Think of Hots/LoL and other popular api trackers where all the statistics are shown.
This is controversial, but I think this is a good way to make the community understand the balance behind each weapon and perhaps what needs to be tweaked.
