That would explain the Seismic Tank the Separatist were using on Dantooine. Literally a Star Destroyer sized piston slamming into the planet. Also the giant artillery piece in early on that the ARC Troopers covered with bombs....like every square foot was a bomb. The lancer trooper and IG lancer troopers are out there, but within reason for the setting (lightsaber, Knights, queens...why not lancers?)
The Mon Cala arc was basically told twice. Once in a simple five minute form with just Master Kit Fisto and the other longer multi episode form which had the actual politics involved, and also involved Anakin Skywalker, Padme, and even Jar Jar with his Army.
Grievous introduction is only slightly over the top. He is that dangerous, since he does have a collection of lightsabers from those he's cut down. He's just not the unstoppable killing machine, that would be propaganda for sure.
