Dead on mate. There is very little point in giving Prism's holofields, they shouldn't be in the direct line of fire enough for them to need the extra protection. Without them you're saving 70 odd points, which is a Vyper with 2 Shuriken Cannons. As Kirbs also says if you drop the stones and the ML on the falcon (i take a shuriken cannon, but that's preference) that's another Vyper, or a change of 1 DAVU unit into Storm Guardians with 2 Flamers and a lock with Destructor. I know what I'd rather have. Maximise your damage potential with points you save on shiney trinkets.
