What with leadership giving morale bonuses now, national commanders that aren't mages are slightly more useful. I'm not sure how viable those "slow to recruit" ubermages will be though.
It's not just that the better leaders give morale boosts; they also let you have more squads w/o incurring penalties. Still, I rarely want more than 2 squads if I've only got 40 or 50 troops. I suppose the real advantage to national leaders is not having a net morale penalty when using the more ergonomic squad configurations for troops without Formation.
Plus, for some nations it's a total non-issue. Say, e.g., you're LA T'ien Ch'i and don't wanna waste a fort turn to get that sweet, sweet 120 troop/4 squad/+2 morale leadership from a Khan? No problem. Khans and non-sacred cavalry are recruit anywhere now. Although that means that no one but someone down to their last 85 gold will
ever buy a General. I've probably missed some of the terrain-specific ones, but here's a rough list of non-fort recruits, some of which
