First of all, Say I fire a projectile weapon, it assumes that i want to hang onto it. I can't fire any Rocket Launchers of any kind, or any sort of Projectile Type Weapon without having to escape from suspended animation, especially when in midair. Firing a Prpjectile in Midair destroys gravity and forces me to hang onto the projectile i fired, and then, im suspended in the air, let go, fall to my death.
Secondly, clipping issues. Noclipping through a floor, or an angled wall freezes me in place, and i cant break through without noclipping repeatedly in the direction i wish to travel.
