Ok cool I will put some more laser repeaters on and give it a go. Thanks.
Honestly, I'd suggest just leaving the weapons stock. The laser repeaters will strip shields fast, and then the cannons wreck. The Mk 3 Tarantula can penetrate 5 meters through the target, applying damage to a volume of just over 2.5 cubic meters which is outstanding for taking out components.
I'm not a fan of the stock component fit; that is definitely are area in need of improvement.
