So pretty much the d-missile and the emp advance are for different tasks
The emp advance is just for disorienting a target for a long time. I'll stick with the d-missile, which most undoubtedly works through the use of emp's also. The d-missile is a lot better because it not only disrupts subsystems, it does it by just shutting down the whole entire target temporarily
Actually maybe the collie doesn't need 100 missile launchers, maybe it just needs the capability to use the d-missile. Cruisers and destroyers are more than capable enough of getting tons of streaming rockeyes to it's target. Why not just replace that with streaming d-missiles, or streaming infyrnos, or trebs for that matter. Overkill yes, but it'd be worth it
I'm still opting for the idea of 100 launchers on the front of the collie though launching 100 simultaneous infyrnos, because that'd be one suppressively destructive huge ass wall of flame
