The eternal question: which heroes are better, mages or warriors?

In my opinion, mages are better. If developed correctly, they can easily defeat any warrior, or almost any...

Except for the Barbarian with the Sphere of Inhibition :D :D :D
As for me, I definitely prefer a battlemage... Magic is more important, but if offered skills like defense, attack, or ranged combat, I wouldn't refuse... ;)
