I will say that I started playing my MCH again today and it just felt clunky compared to my Samurai. Hoping this changes at higher levels, but I can see where overheating is an issue even at 60. You overheat and you lose the 5% damage buff for 10 second PLUS the potency from heated rounds during the time it takes to get to 50 heat. The seems like the only class where a base mechanic punishes the player so harshly for what could be a single mistake.
