I still like the idea of GotE's as different specialties and their "body guard" as an option of either an extra hero slot or any one unit of special being counted as core whether that's an extra cannon, mortar, greatswords, or even inner circle knights, pistoliers, and outriders.
The elector count upgrade could work but it does play into the whole powerhammer baloney, by essentially paying for the runefang it still retains some of the game balance. Hell why am I worrying about it GW doesn't.
