HFs with Class 7 hardpoints are weaker than VHF and even LF. They cannot stand the heavier damage and powerplant of VHF, they also have problem with the agility and high damage of Class 6 weapons of LF. Pulse-missile combination also doesn't work effectively because LF and VHF are able to use the said combination too, especially class 7 pulse weapons are inferior to their class 6 & 8 brothers.
I suggest that HF's hardpoint capability should be turned into that of 'multi role fighter' or 'jack of all trades' class like this:
3x class 7 guns hardpoints
2x class 8 guns hardpoints
1x light missile or CD hardpoint
1x light missile or torpedo hardpoint
This light missile is a damage reduced version of the current missile in disco(cannonball, paralyzer, etc). This hardpoint capability allows variety of combinations of weapons in HFs while not considered OP at the same time.
