A decent Medium 'Mech, but not something I'd use in favor of more classic designs like the Nova or Stormcrow. Despite the existence of the Shadow Cat, the Primary configuration strikes me as something I'd use somewhat like a giant Mist Lynx. Good for heavy recon and capable of handling just about anything it encounters thanks to the surprisingly heavy armament to go along with the maxed-out armor.
Unlike everyone else, I cannot stand the Alpha configuration. Pulse lasers as primary weapons for the Clans have always struck me as the mark of a poor warrior due to being used to compensate for lack of skill (and, yet I don't mind them on the Mad Dog Prime, go figure). Bravo is probably my favorite configuration, though. A potent mix of a PPC and heavy autocannon plus a decent secondary armament. My only issue is the giant ammo bin for the twin machine guns. Charlie is workable, but it just bugs me due to the mixed LRM racks and tiny ammo bins for its three main weapons. Delta I actually like, mostly because I have an unhealthy fascination with the Class 10 autocannon in any flavor and strikes me as more of a partner for the Bravo. I've never used the other variants, though. Mostly because they don't strike me as anything I'd really want to or enjoy using. I may end up giving the Echo a whirl someday, but the over reliance on pulse lasers just bugs me.
