Swords and partisans have the plus of smacking 10 enemies at a time where as shots hit 5. If enemies are up close in personal and in numbers in a small room I'd rather use a sword or partisan than a shot cause fewer enemies will be able to sneak by. Not sure where slicers are slower than shots come from though. I could of sworn that the cool down time for almost every class was faster on slicer than a shot and the blades on average come out at an ok speed, I mean I'm able to get a combo off a slicer by just stepping back easily enough. If they are slower in that their range isn't as good as a shot and they also only hit 4 enemies vs the 5 than sure but slicers like rainbow baton, charge diska, and sof are pretty low risk in single play.
But yeah needles (mostly cause of s-ranks though), frozen shooter, launchers/bazookas are a sort of far better unique weapons than anything daggers, twin swords, and double sabers bring to a Hu. For sure when the strongest of those types are being used by Ra as well anyway like Daylight Scar. And partisan wise yunchang isn't so much better than stuff like Tyrell's as well (the average is 20 or so base damage so yeah).
Then again its not secret that sega didn't balance the classes right when it comes to Ra. Needing smart link is a unique disadvantage for hu and fo and nothing else is like it in the game when stuff like having a much higher ata sort of explains that Ras would be better with a gun by default anyway and then stuff like ranger wall being around is another thing.
Though again my main thought is on Hucast vs the rest of the Hunters. I just don't think that raising their atp is that good of a fix. Hucast with his max atp sort of combo kills a good % of the mini bosses in the game as it is with just vulcans and freeze traps and 20 shifta or so and in case my example didn't tell he can combo kill a goron detonator as well pretty easily by just freezing it and pumping it with nss if he has level 30 shifta and the monster has level 30 zalure. Player vs enemy is already pretty manageable for single for hucast cause of that factor alone. I mean there is a 40% difference between fomar and humar in base damage when humar has shifta 30 and zalure 30 around but that power difference is pretty much 2x that for fomar vs hucast. Buffing 3 of the classes when in truth you could just do some small nerfs to a 1 or 2 Ra (though Ramarl is pretty balanced IMO) and produce a better affect seems better to me than making player vs enemy even easier than it already is.
Fomar and Ramarl can pretty much solo everything if given enough time and pretty good as well. But in truth Huney can solo everything as well. I mean she is doing an extra 75 damage or so vs Ramarl on average and she does have rifle range with holy ray so it isn't like things are all but horrible for her solo. Humar is suppose to be the games "most balanced class" so it would make since that he would be next solo damage wise but he does have to manage his stuff a lot. But Hucast sort of breaks the mold some IMO.
Though in the end this is all theory I'll admit.
