This is as perfect as I can tune this chassis. I have spent a long time with this mech, and when used as an extremely aggressive poker, this mech will regularly outperform assaults. It may seem like I've stripped all the armor off, but the quirks add so much free armor that your durability matches that of a 30-35 ton mech. So long as you maintain situational awareness and keep to cover, you will find that this mech is very hard to kill.
In my experience, the difference between the xl 180 and the xl190, while large on paper, is not missed in action. The way I pilot this mech, I don't circle enemies or stay in view. I poke in and out of cover and tease the opponent with constant accurate lpl fire. Used in this way, I generally never reach top speed, and the difference in accelleration is not noticible. I do, however, notice the increased damage output from having an MG lying around for all those opportunities where my point of cover is really close to the baddie. I have spent a very large quantity of time with this mech. This is the build I get the highest numbers with.
