Nope. That's why I think they have potential. I do agree that the vast majority of the time it would be better to downgrade your firepower inh favor of being able to use it repeatedly, but in those rare cases where something is more interested in getting some heavy punch NOW, iOSes can compete with RLs due to the different properties of S/LRMs vs rockets, and their ability to be loaded with various ammo types. Honestly, my favorite use for an iOS rack would be as a Handheld Weapon, giving even light 'mechs a credible long-range shot before they close for the main fight. A sort of 'mech-sized LAW, as it were.
