_ Well since the Quarantine is free and we can expect to see alot of interesting and great builds, so I thew my hat into the ring as well. The SSRM6s are great for dealing a good amount of damage against lights but you have to be frugal using them due to only having 1 ton of ammo. With the RAC2 and 3 MPLs deals a good amount of damage to targets just watch that heat with the RAC2 running while firing the MPLs the heat dissipation is really slow. So get yourself a cool shot and watch that heat.
Tried something like this on my Quarantine and failed. Maybe it's just because of my play style, but a single RAC2 doesn't work for me on this Mech, too much time when I was exposing myself to the enemy without getting the benefit of overwhelming damage. Of course if it works for you, run with it and have fun.
I feel that with this kind of build/mech you'll need to have free look mapped to an easy to reach button, so you can aim your arm without exposing your entire front side
