The rpg is meant to be hard to maneuver so that you don't perfectly hit every vehicle no matter how much it's trying to dodge.
That's true. Even when you're aiming the best you can, the rocket keeps making a circular motion whilst moving forward, making it a wild guess where exactly it will hit.
I like the missile laucher currently:- it's tough to guide like the mortar is a tough weapon. it's all about how you use it. -use gentle movements. -always lead your targets, because otherwise the rocket will be impacting from a really side on angle from your view, and that's really hard to get the rocket right -stand still, atleast while learning. i like to crouch. -learn that it's not like the easy to use HL2 rocket launcher.
