35 point alpha, shield with arms between shots. 2 MLas backup for chasing away pesky lights. Weapon Groups 1: Gauss 2: 2x PPC 3: 2x MLas I don't macro so it's all manual on the syncing. You have to tap 2 just slightly before releasing 1 as the PPC projectile is slower than the Gauss slug
I have seen this build around for a little while. It can be a fantastic build in the hands of a sharp shooter. The main drawback, obviously, (other than the speed differences between ppc's and gauss) would be not having jump jets to pop-tart in so that you can get behind cover while your weapons cool-down. That being said, I think if you were to move a few things around and downgrade the engine you might be able to sustain the heat in fight a while longer. I moved the second medium laser to center torso for zombie-mode. I do believe you could easily swap one if not both ppc's for the erppc's. edit: you could also keep the ppc's and drop a heatsink to add extra armor or 2 heatsinks to add ams and a half ton of armor.
Gauss is a bit fragile for an assault mech's torso IMO, and the AC20+PPC combo is battle proven (if recently nerfed) in the Misery.
