I still really think Zmey's should have the 'cold blooded' trait.

That way it wouldn't be a good raider in some situations.
This is a good thing. As Dom3 is about strategic thinking and planning ahead. Having access to a good general purpose flying raider makes it a boring unit. The way it is now, it lessens diversity among nations.

This might also be a problem by giving all nations access to all Sombre's Summons. It might reduce diversity too. These summons would preferably have to be powerful niche summons as to not make national units/summons inferior.
