That thing WRECKS. Go for full heat gen, cooldown, ammo and tankiness. Those AC5's shoot so fast thanks to the 15% CD quirk. And the damn thing is so tanky... Much fun.
I like this. Similar to something I'm doing on a MAD-3R but lighter. I just saw someone in FW using one of these, but he also had an MRM, so must have been running an XL. Removed the TC and increased the engine. Leg armor is important too with all that ammo in there.
