Problem is it just seems terrible on so many levels
I think you could make quite a good army with Kharn and berzerkers as your troops, but with two or three units of berzerkers maximum (in transports). Then almost everything else would have to be fast pressure units like bikes, maulerfiends, flesh hounds, maybe a bloodthirster etc.
If only the formation was something like Kharn and three or four units of berzerkers, with the formation allowing you to assault out of rhinos. As it is you'd pay a massive amount of points for units that are great at killing infantry but not much else
