I would try to summarize what this "suggestions thread" has proposed at the present time.
Incipit:
MA Oceania would probably benefit thematically and in nation strenght from a slight improvement, hopefully towards an appealing "raging sea/storm" subtheme (tnx Baalz).
Valid proposals:
- More sea summons: giving the oceans a wider amount of natural, wild creatures to summons, like the land nations get. Just some things from a list including Orcas, jellyfishes, manta rays, a sea serpent, amphibious sea turtles (for an high protection longbows-crossbows counter to start conquering the land), swordfishes, narwales, barracudas, manatees (?)...
- 1/2 recruitable (coral?) chariot(s) lead by dolphins/ hyppocamps for an underwater shock force. (Spendios)
- Ichtycentaurs to become a good (possibly better on land than on sea) amphibious unit. (cleveland)
- Shell blower: this could be a national summon (as recruitables would be probably unbalanced) which acts as standard and can cast panic 1 or 2 times before going melee. (Wrana)
- Selkies. Those are the main piece of the raging sea/storm subtheme suggestions, as they would provide the "storm" (A/W strong mages) factor we're looking for

(Baalz)
Somehow discarded suggestions + explanation:
- Scylla: it is already in game as the (lovely) Drakaina pretender
- Hyppos and crocodiles: Nice, but they live in swamps, so they better fit C'tis or the other "swamp-nations"
- Piranhas: nice suggestion but they live in rivers, not oceans
- Ammonites: I think everybody agreed they fit more as a death/water summon, nice but a little far from the air/water suggested subtheme.
General, IHMO quite nice, suggestion from different people:
- Thetis' Blessing working both ways: so strategically interesting i wouldn't bore anybody talking about it
Peace
