The reload time on them is part of their balance, to make them not be completely overpowered. That’s the trade off. You can hit pretty hard for twenty seconds or so, then you better either have killed the target, kite off or tank until you can finish him.
Such a long reload time means the target has a full 35 seconds to just repair any damage I have done, even if I have enough (non reload) DPS to kill them.
I support this idea, there is no balance here because the rapid launchers are crap, I’m better off with the proper sized launchers and removing a bit of tank for application if I’m expecting smaller targets. I’ve never looked at a rapid launcher fit and thought “yep, that’s good.”
