I'd still say that you overemphasize weaknesses of Bogarus. While their infantry IS bad and sacreds are worse, cavalry can actually hold their own. As for late game - they have good enough unique summons.
I also see that the idea of Patala as the worst-troops nation have been deservefly buried. As for EA Agartha - their Troglodites are excellent rushers in their own right, needing less support than Elephants do.
