Hum so non death nations not only need water magic but also a water gems income (or air magic + air income or some alchemy) to begin any underwater expansion (except with amphibious poptypes, but having amphibious poptypes 1/ it's a matter of luck like having indie water mages/gems sites, 2/ doesn't give any advantage against indies like magic or the ability of using sacred troops + priests do).

It's a very big buff not only for aquatic but for death nations (and I'm not really thinking one or another needed it, but perhaps it's balanced by other factors like weaker national summons or other things we can't see before playing).
