Sounds fishy to me. I've been using ML's on my JD & Scout to kite higher level mobs lately, for maps. I can barely hit things 10-15 CL's above me, as have the rockets do 0 damage, or miss entirely. On top of that, your reactor runs dry after a couple minutes, which equals less missiles being fired.
How much combat xp did this yield, and what CL were you?
