Here's a question about the efficiency of skill development.
If I'm playing as the Academy, I take the Knight. I've tried two development paths:
1) Sorcery - Education - Light - Darkness - Summoning
2) Sorcery - Education - Light - Summoning - Defense
The hero is maxed out at level 24. In your experience, what's better for the Academy hero – three magic skills or two magic skills and Defense?

P.S. The opponent isn't a Necromancer, so the question of Darkness is irrelevant.
