I think as a heavey magic user that there spells that only a good person can learn and spells that an evil person can learn I think that would be very cool 
and i also think that they should upgrad assassians rush in the sence that in the lower levils of the spell it is normal but if you max the spell then while the spell is in motion i think it should stab the guy in a backwards motion that would be very cool 
and sorry if someone has posted somthing like this i didn't see it !
