The EU thing about Stormtroopers being limited I think was based on the assumption that they were an elite force, and that the guys in the big helmets and black shirts were the 'regular' army. However, judging by the prequels, Lucas I think intended them to be the main army of the Republic/Empire.
Sorry, but it is very difficult to take the storm troopers seriously after witness how inept they are in RotJ. They were poorly trained, uncoordinated, and absolutely disorganized.
SW.Republic Commando was a great game, but EU is EU.
