I think
Officer - General - Marshal
As I also love the TW games, I play on the 'officer' level, I like to see what's going on and enjoy the whole battle panorama and waiting and waiting for Corps commanders to react to an order has me biting my Shako in rage!
Playing the game from the Commander's view point only and not seeing anything of the battle, with only the 2D map with FoW doesn't give me much enjoyment....each to their own...
Glad this game has such a great, passionate fan base already, JMM must be pleased!
