don't add the pawn's velocity to the projectile's velocity. this makes no sense if the pawn's velocity is perpendicular to the projectile's velocity (e.g. for side turrets or when the pawn is 'strafing'). if at all, only the part of the pawn's velocity which has the same direction like the projectile should be considered. but this still makes projectiles unpredictable because they have changing speed. so better don't do it at all.
