If I was a water nation, I would consider Sea of Ice a violation, at least if I hadn't been consulted.
How about the random attack ones? Not that they're cast very often in MP, but Wild Hunt, the random lightning strikes one and isn't the Ghost admiral a global?

Dispelling a global would be a violation? How about stealing one? Casting a different global that overwrites yours due to a lack of slots shouldn't be, but overcasting the same one?
