at lvl 100 you should be doing K95, K99, Balok, Baylor, CC, GC parties some are made some are not - Daily's like you said. its best to make a DD with your healer with a ISS I am thinking to go along with your healer - oh Spez you can do, some other Instances with a party. Maybe Hellbound not sure if there are parties there these days for Nobles quest Exulted.
