Rocket Launcher Exploit Rapid Fire
The new rocket launcher can be exploited to have rapid fire by putting both different rocket launchers in the hotbar and firing them by switching between them by switching back and forth.
I suggest a priming feature to have the rocket launcher take the full reload time to be ready to fire once you switch to it. In this case, it could be that if you put away the tool, it empties its ammo back into inventory, or drops the rocket into space if not enough inventory space. Basically, the rocket can't be loaded without it being currently held.
Then switching to it, will switch to an empty rocket that needs to be reloaded. Switching from one to the other, unloads the rocket you just held. Thus removing this exploit in the simplest way.
