Haven't seen anything about the Generals/Governors. Maybe i haven't searched well enough though.
I liked the idea of Shogun II, with one General and a skill tree, where you could clearly favor in different directions.
Rome I with auto-traits popping up every now and then, retainers gathering, then "giving them out" to a younger general, so as to keep them wasn't to my liking.
And even for battlefavored General, i hope they continue distinguishing Strategist types ( Shogun II : +X moral for all troops, new formations, etc...), from the Brutal ones (Shogun II : +X armor for the bodyguards, more bodyguards, more hp, etc...). And maybe make the "brutal" one more even with the Strategist. You just "had" to take some obvious skills for formations, and all troops bonuses are way better than just 30 tough cavalry.
Yes, i'll play RTW for the battles more than the diplomacy and management.^^ Though i like developping my provinces, and how diplomacy is sometimes necessary.
