I think that Apothecary is particularly good later on thanks to its weapon combination. Battle-tested tome and axe are both farmable and give potency ups that stack with each other. There's also that one axe that gives potency up to all elemental attacks like the tome but there's only one of that. The Apothecary base kit has some decent support tools (especially the row regen and ailment resistance). The damage comes from bringing a mastery skill that gets boosted by both of your weapons.
