i think all we need is a controlled rocket, default RL, and a guided rocket that follows your aim and goes toward it
for the controlled rocket, it would only have 1 be able to be fired at a time, as you're aiming it like a plane, and for the controlled rocket and the guided rocket, they would explode on jetting
rocket shotguns/heat seeking/rapidfire seems a bit much, without much user controlling/overpowered
