Buffing my Nataraja

[magnate]

I've taken E2W2S2 on my Nataraja (I know, you wouldn't take S2 in an MP game - this is SP) - I can't decide whether I need A2 as well. With A2 I can have Mirror Image at Alteration 2 along with Quickness, Luck and Stoneskin. Then at Alt 3 I can have Mistform along with Quickness, Luck, Ironskin and Body Ethereal.

The thing is, once I start researching Enchantment I get the awesome Astral Weapon and Astral Shield, which will replace the Mistform and Body Ethereal (would anybody advise me to replace Quickness, Luck or Ironskin instead??). So the air magic is only useful for the period between Alt 2 and Ench 2, which will be all of about five or six turns.

Would you do without A2?

Or would you take it and not bother with Astral Shield and Astral Weapon? ie. stick with a script of Quickness/Luck/Ironskin/Body Ethereal/Mistform and get straight onto researching construction?

(Suggestions to grow up and stop obsessing about this damn game not welcome)
