Wait a second; isn't that against the Kaggath rules?
People like Revan weren't allowed generals like Saul Karath before. How come Sidious is getting his generals?
This fight is a little difference, for one they won't appear in the tournament because they are simply too powerful, and secondly its the grand finally - so I thought I'd up the anti here. And besides, in the scale of things - how promiment is a few Moffs in comparison to the galaxies greatest Sith Lords?
We also need to really consider the importance of having a sith army - Sidious has few if any weapons to defend against the full might of a Sith - apart from himself and sheer firepower.
EDIT: People have mentioned Dark Troopers, Shadow Guard, etc. but how do they match up in terms of numbers and power?
