Seriously, see title. I see people having successful runs with it, and some people even considering it mid tier; why? It's fast, but lightly armed and competes with the Shadow Cat (more free tonnage), Viper (the chef), and Arctic Cheetah (best light mech in the game) for that. I'm pretty confused as to the role of the fridge.
I can't tell you how it does perform as a brawler, but I've seen it being used very well as a fast med-long range harasser with ERLL / HLL in scout. As far as I can tell, is really one of those mech that you don't want to chase if you are a brawler, because you are gonna die for sure while attempting to catch it.
My best results are from using it like a light mech. 4xMPL is how I use it. hit & run and come from a different angle every time.
