Dual wield wouldnt really fit a WHM main since its trait mainly for ninja and thf/dnc really.

Banish tho is something that WHM should have up to max tier as its the only real offensive spell whm has. As said before the last spell in that line WHM gets is at lvl65 yet mobs and npcs not only have the -aga 3 version but high tier use banish 4. Why WHM never got these like blm got tier 5 nukes is a mystery so far.

Its no harm for Whm to have max level spells anyhow and its one of those missing leftovers from the level cap raise.

Also Blm should have tier iv aga elemental spells as well.
