Air magic has some of the strongest evocations, thus its summons were weaker. But even if we are to buff them, why would a conjuration 6 summon for mere 15 gems be so much better than a bane lord?
Give air nations a summon that is better than death/blood summons, and what do death/blood nations have for them?
I just think this alternative is too strong. I am going to play a game with this mod now, as a death nation. And I am fully going to take air for my pretender, and pray for air sites. Because until I can get tartarians, death doesnt even come close to the Shishis.
