If I understand correctly what Hekasan was talking about, then it's Ammmon, Alira (whose only ultimate ability will be displayed), Khilar (whose only kill ability will be displayed), as well as Falmer and Mother, who don't have any normal abilities at all + mages, whose Cassandra is not visible in most cases, and various ultimate abilities. And Iman, whom we haven't even seen in the newspapers yet.

and it turns out that these are Falmer, Ammmon, Leila, Grimbol, Khilar, Ariel, Alira.
