Honestly, Bane has it right imo. HVO has proven to be a bit of a fail, it's underutilized, has limited slots, and is just taking up a job per battalion. Give the launchers to ARF (which high key needs a buff anyway) and call it a day. As for the mines, they've been causing more problems than they've really been worth. I'd remove them from most of the kits, maybe leave them to the "lore HVO" classes like Nate and A'den and such?
or y'know, split SUP back into ENG/Pilot and give the Engineers Anti-Vehicle mines, but that's a story for another suggestion.
Maybe people will start taking ARF a little more seriously and they'll actually get some love. +1
