Mage Comparison

[Hento]

I was wondering how other people developed their mage, mine is level 18 with following characteristics:
-33 intellect, the highest damage spell is ice snake with 4300 damage.
-level 3 chaos and order, level 2 distortion, level 2 higher magic and level 3 destroyer
-25% experience
-1 level onslaught

I pretty much destroy all armies(fatal and stronger) in 2-3 turns without any losses so I think I couldn't have developed it any better. The only problem is that I always lack mana despite having 125 already.
Also I was wondering how much damage would a warrior class do if it has 33 attack instead of intellect, because with this mage I do more than 10 000 damage per turn just with spells.
