In my opinion EA Agartha is as good underwater as on land. They have flaws in either sphere (like cold dominion), but are still competitive and certainly not easy victims. They've still got fully effective bless troops, thugs, most of their magic is as good. Note also Baalz's comments that sea nations have an advantage that they can usually assault a coastline with almost no fear of reprisal, which doesn't apply to Agartha.
