the game mechanis of WHFB are ok the magic phase has ruined the game, thats why a lot of tournaments in the UK and Europe have comped the magic phase big time.
I have done a load of files and stuff for Hail Ceaser fantasy with magic as a subtle add in depending on race, wizards are bought as upgrade to command base and an order required to get spell off
orcs = missile spells in shooting phase
elfs = illusion and tricks movement increases in movement phase
Human = a bit of the above
undead = heal in command phase
that type of stuff
