Best Proxy Ogre Kingdom Faction

Inspired by the recent Okoii's 19 Ogre mercenaries video, I got thinking - given that apparently any faction would be able to hire Ogre mercenaries, what would be the best faction to use as basis for an Ogre-units-only campaign?

Presumably, there are two (three) main priorities:

* Income. Feeding Ogres ain't cheap, and to field whole armies of them would require only the strongest of economies to work. Obviously, this is where economy-cheesable factions would shine, and unfortunately, this also presumably disqualifies Tomb Kings - they are awesome, but if Ogre upkeep is constant for all factions, they simply won't be able to have enough income to support fully-Ogre armies.

* Faction-wide unit buffs. They are less common than unit-specific buffs, but that's the only way to make our Ogres even better - and the reason to pick this faction over another that can afford Ogres better, but cannot *support* them better.

* (bonus) Faction-wide campaign buffs. These are less critical, but can also come handy.

All said, I think (surprisingly) one of Bretonnia factions can be the best for Ogre-by-proxy-Kingdoms playthrough. Their economy is nice, theoretically cheesable, but the most important factor is the lack of supply lines - and, of course, Ogres not taking "peasant" limit. Buff-wise, there are T4 armouries (that should affect even Ogres in your employ), there are some army-wide character traits, notably for repeatedly reinforcing in battle (IIRC, it gives +speed% and +charge% to everyone in the army - the latter should come particularly handy to Ogres) - and, of course, Blessing of the Lady giving *everyone* in the army +20% phys resist. "Friendship with Chivalry ended, Now Gluttony is Lady's favourite virtue" ^(Provided there's not a last-minute general ban to hiring mercenaries by Bretonnians, true to tabletop rules.)

Any other good candidates for Wh2 "Ogre Kingdoms" playthrough? :)
