Honestly, the HF issue (and LF) has been a big problem with me too. If VHFs and superiority fighters, and LFs are "interceptors" (Ha! hardly, but don't get me started on that) then HFs are what? Cheap VHFs?
Honestly, I would put all the mkII heavy fighters like templar and chimera into the HF category, make HFs the superiority fighters, and move the SHFs to the VHF category, and remove the SHF category once and for all. Other fighters in the VHF category might be, say, the executioner, the nepthys, etc.
