This started out with a standard AC10 + 2x LPLas build but which I didn't liked as much as I thought. AC5 + SRM6 offers a better punch and better DPS and happens to fit the mech at the same speed. Relevant quirks for this build: Dragon Fang 60 (5) - Torso Yaw Speed 10% - Additional Structure (CT) 24 - Additional Structure (RA) 6 - AC/10 Cooldown 12.5% - Ballistic Cooldown 12.5% - AC/10 Velocity 12.5% - Ballistic Velocity 12.5% - Large Pulse Laser Cooldown 12.5% - Energy Cooldown 12.5% - Large Pulse Laser Range 12.5% - Energy Range 12.5% - Energy Heat Gen -15% The XL 300 provides enough speed for Dragon style flanking runs, but the mech is also capable of doing a lot of mid range fire support by simply using the LPLas. I was able to do several near-1k-matches simply by peeking with the mech's left side, double LPLas into target and vanish again. Don't put both LPLas into the left arm as those arms seem to take a lot of damage, at least for me. The LPLas are your main weapons (your blue claws), so loosing them WILL hurt. I highly recommend getting both the LPLas range and cooldown modules. The AC5 fires fast enough and has enough range while the SRM6 should only be used at ~200m or while doing close range strafing runs.
