I just think that each race has its own predispositions, so universalization in this regard is not always a good thing!
I used to think so too, but then I noticed that when you play, for example, as a Dark Elf and you max out attack for mass speed and logistics for surprise attack, the tactical possibilities are greatly expanded! But, in general, you don't use these spells very often, and if you do, you'll regret it later: "Oh, I should have used Chain Lightning or cast Meteor Shower instead..."
The same is true for many races. Why does a demon need Chaos magic if he can masterfully cast all mass spells of dark magic, and his magic power is only 6? Wouldn't you rather use mass slow or berserk to deal 140 damage to the enemy with lightning instead?
Decide at the beginning of the game which tactic is best to follow and stick to it... why have extra things?
