Im gonna disagree with you here, Its a dumb idea to attack the seismic turds that litter sats with this loadout, but its not as bad as you're saying it is either:
its not about "synergy", the benefit of running ions/clusters/HLC is having both a medium and a short ranged counter to enemies. With ions and clusters, you can put power to engines, and chase scouts down using ions to strip shields and clusters to finish them, conserving your blaster pool. Heavies are for anything that gets out of your 5k ion/cluster range. Its a general approach instead of over specialization, which comes in handy in a T1 SF which is kind of made to be a generalist spaceship. You have the ability to use two primary weapons in a starguard/rycer, why restrict yourself to one range?
Also Rapids suck so hard, and should never be put on anything, much less a strike, which has so many better options.
