Juggernaut Adjustments

After finally seeing Juggernauts in action (seeing two of them rape a full escape shuttle) I've realised their laser reflection is a bit much.

-Raised the reflection chance to 80% from 65% -BUT-
-Instead of the reflection nullifying the damage entirely the juggernaut takes half the projectile damage
-Adjusted the weighting on the reflection trajectory, the intention was meant to be more "ooo sparkley light show, oops sorry dude over there" than "I shoot you, I die"
