I ran it last night and it performed pretty well at short/mid range. Good and precise damage, not so hot (and I haven't doubled the perks yet), manoeuvrability is ok. Just a little fragile, but I feel this on every mech. The choice of a standard engine increase durability (I ended a lot of matches with a side torso destroyed). This build is kind of a nobrainer for a laser boat QKD, and I don't see much room for improvement and tweaking (you can remove some armor and/or JJ for a bigger engine, or AMS). See the "Fast Energy" variant if you want an XL engine. One more thing: it's cheap! Approx 6.5 millions.
