It would be nice to see an alternative plasma caster charge introduced. Currently, we can only charge by aiming first. This displays the helmet targeting lasers which gives away the position of the predator. This also leads to players aiming at a wall and then side stepping to then expose the laser before releasing the charge.
Why not use the fire button without aiming. This could only be used to prematurely charge the PC so that the PC could not be spam fired. This premature charge would allow the Predator to remain stationary and then at the opportune moment aiming can be introduced for a perfect shot on an unexpected fire team member.
