First thing I see when I see VA is Resourceful. Second thing I see is them being divided up into a mage VA or a melee VA. And from that you'll probably use like 3-6 skills at the most, 3 of which are covered by resourceful.
From there, you'll grab the utility stuff from your sub class because you've already covered your main method of attacking.

Classes that come from duelist are usually full of innates and equip like 3 things and grab PG, riposte, and fluer from duelist itself.
BK will most likely just grab hanging, every innate, and with whatever points they have left they put into steel mind/body etc. You probably won't even touch soldier skills.
Verglas depends on build but a cel focused verglas just needs ice point, greaves, and rapid kick. Str verglas doesn't care about anything in particular since their moves aren't as useful without chaining into a different style (which means a mixed build) (and verglas has will growth on top of that)
Monk also depends on your build since they have a variety of scaling like Verglas and all you'll grab from MA is shukuchi, heaven kick, and meditate if you have a lot of skill.

And keep in mind, low will means a low FP pool so these melee classes don't even want to grab a bunch of skills since they'd much rather prefer abilities they can always make use rather than being limited by their FP and unlike mages that get a variety of different elemental damage, the only real variation for melee is either being an auto hit, a crit, or doing magic damage to bypass high defense. So once you cover your bases all that's left is utility which is mostly in innates.
