It's more reminiscent of this than a cloak/hood. I'm not discounting holy warrior. Just with the nostalgia angle, I'm sure it's a Paladin. I wouldn't mine seeing a Cleric type that opens up for some melee/caster version, I know both Paladin and Crusader have had ranged stuffs, but they have been primarily melee. But my guess is pure melee tanky class.
That way we start with physical pure melee -Barb. Pure magical ranged - Sorc. Hybrid physical melee, magical ranged, pseudo pet, tanky - Druid. Hybrid physical ranged/melee, agile - Rogue. Magical melee, tanky - Paladin.
That's a nice well rounded set of classes. Still missing dark magic user, pure pet class, pure magic user sword and board, and pure physical ranged.
Still going off nostalgia and existing lore, we have Necro, WD, and Amazon with room for a brand new class or a reimagining of older classes. Not to mention they can go in a different direction. My bet is Necro will be the first added class though.
