Hard mode? No magic, all roles done (including AoE control).
Alternatively: stay away from charisma and Dex based multiclassing.
I can really see Palalorcks be positive here... Also Bardadins! I think I already have a build on this theme "Stab of all Trades". Both the T-44 tank from last Throwdown, and the Caster's Bane, both fulfill a lot of the criteria.
