Air Dome

The additional gem domes don't break, so you only need one in a prov, I don't see any imbalances. If you want to burn 50 gems per province stacking up multiple air domes I think you've pretty much already lost that battle, especially since a spell still has a 20% chance of getting through since only one dome is actually checked, so it doesn't make you any more resistant to the heavy artillery spells (flames from the sky and murdering winter) than a single dome would.

Maybe 10 is a bit extreme, but having a spare or two in waiting could be handy.

Depends, in late stage of the game people usually concentrate most of their troops and mages in a few forts and protect them with all kinds of domes.
And with the air dome being the cheapest and most effective, stops 4/5 spells cast, having more than one surly is an advantage. How much does flames from the sky cost? or any other spell you need to break the air dome? VoD is the cheapest and yet you'd be using 15 gems on average to take out a 5 gem dome.

But also what if you only have the ability to cast nature dome with Pangaea for eg.? Casting a few more would be safer.
With Cealum also.
