Decently fast and jumpy. Nice armor other the the right arm. Runs cool usually. Enough ammo for all the match. I find all the weapons on the same side pretty much needed, with all the firepower on the battlefield that clan mechs introduced, you can afford to expose for very little time with an IS medium, let alone one with XL engine and gauss, much less then you could before, and you need to pick fast shots using the weapon convergence, so even if the 5M is able to copy the build on the paper, on the field it can't be nearly as effective. 25 Pinpoint Damage up to 660m.Pretty good numbers for an IS medium.
