Detailed, highly specific analysis has proven standard QP NASCAR speed to average at 69.69 km/h. While the methodology used is proprietary and will not be disclosed, rest assured it's completely accurate and impartial. With that fact having been established, now you can see how a JR7 moving at 78.7 km/h is perfectly acceptable. You're quick enough to play escort to your assault mechs', by which I mean you have on average 300-350 tons of "meatshield" before any enemy should focus fire on you. Just target what everyone is shooting at and deal up to 72 damage as your contribution.
Original build? https://mwo.nav-alpha.com/mechlab?b=3723929a_JR7-IIC Fast build with jump jets and cLAP. https://mwo.nav-alpha.com/mechlab?b=15789742_JR7-IIC Spoiler Works out ok if there isn't AMS and stealth around. Ammo is an issue.
