Well if you are taking Air for Aim/Eyes of Aiming you may want to go with a Phoenix. They start with the 2 paths you want (Air/Fire) and you can more affordably raise your Fire/Air if you want more than 1 in Air.

If you are going Air for Eyes of Aiming (which is my suggestion) you would be better off to get 3 or 4 in Air to find sites to create them.

Nature gives you Berserk (which stacks with the Lava Warriors Berserk for additional) that gives you +Prot, +Att, +Str, +Morale, -Defense. Plus Regeneration and poison resistance, whereas Fire gives you +4 Att, and Flaming weapons to hit Ethereal beings.

Taking Turmoil is going to hurt your gold income and you are going to have to be able to compensate somehow. Air also gives you quick access to Patrollers via Call of the Wind. For better blood hunting.

All in all; it's how you play the game. Though personally I wouldn't focus on bless effects before I knew how to play the race without using bless effects.

My suggestion to you would be to play Abysian with a low power pretender and high scales and see how to compose the quickest most viable armies and what those armies weaknesses are. Then you can make your pretender to fill in those gaps.
