that explains a lot.
i did had in mind rebellion for the 3 major factions that heavily influenced history with their own civil wars (Rome, Seleukids and Ptolemaids), but if the loyalty is the only parameter available it might lead to counter productive effects, especially for the roman faction. and if you can't pick a side you might end up playing an unwanted side in it (usually loyalist), that would in this case mean playing as the senate against your most powerful generals. i can't vouch for others, but when i play TW, i identify myself mostly with the field generals then the home administrators, and in EB1 my preference often goes with the hired "allied" generals, as they often have more desirable traits and are faster to improve.
