To be honest, it depends on your faction. It would be completely insane to try and play a steppe faction using the general cam, since successful horse archer strategies require wide area unit dispersal. And it's impossible to manage this with the general cam (and those factions are already hard enough as it is...this just shoots degree of difficulty up into the stratosphere!).

On the other hand it's definitely the way to go with most of the infantry based factions. Although if you have an infantry general (like the sweboz), it's very difficult to follow what's going on.
