So, I kept playing, and I like the campaign story missions as well as the freelance stuff. I'm a few main missions into the game.
However, I still don't have a mech that I like. This is a problem. The light mechs seem like they could be fun to use, jumping around and engaging vehicles, hitting turret generators and such. There is no tonnage limit though, I rather, I am nowhere near hitting it, so why would you ever use a light mech.
