I answered Abysya (both themes) and Marignon (all themes except CotS, I dislike that guerrilla raiding).

I like Ulm too however, except the BF theme.
And I'm getting in fond of Pythium even if not liking it a lot, since I notice in a game my allied player Pythium is doing pretty well where I often failed.

I find them to suit my gameplay.

I like a lot blood, and strong national troops, usually HI and Cavalry or both of them (I like a little Man, but infantry isn't so heavy and disciplined.)

I believe my choices are not 1st tier, since I believe they're Ermor and Air magic based nations like Vanheim and Caelum (I dislike them a lot because they're too strong IMO).

I like too Arco because I'm fond in ancient grece too, and ancient rome ... well I'm Italian, my land is fullfilled of this ancient lore.

I dislike what I see as mass poorly equipped troops like Mictlan and Machaka (well big spiders aren't so mass ... but ... I like humans - I considers Aybsyans uber-humans elite troops).
I love hand-to-hand combat and dislike those michievous raiders like Thuathas and Vans.
Don't like too to be under sea ^^

Well probably I expanded my answer to my feelings about many races so I stop myself there.
