Interesting. I would certainly consider giving them high MR units designed specifically to deal with Ryleh. After all pureblood Oceanian tritons naturally have good mr.

Perhaps something like,...

Oceanian Depth Rangers. Stealth 0, high mr, patrolbonus. Their task is to tirelessly roam Oceanian waters hunting down spawn, hybrids etc. They are semi elite with some extra resistances gained by fighting all manner of horrors. They have been known to launch raids deep into Ryleh in order to strike down foul temples and powerful Illithids.

I'm thinking that LA Oceania would be a nation on constant alert, always ready to strike, to retreat, to counterattack. An assassin form of the Rangers might be nice too, for killing illithids.

What about amphibious troops? I think mermen are a constant in Oceanian history, so I don't mind having them. As for the halfmen of MA Oceania,.. eh,.. then there's Ichtyids - they might be interesting as part of a new oceania.
