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

Battle mages are the best. Sometimes, the battle is decided by magic right at the beginning.
But what's bad is that not all spells fit in the book - I was playing the Dragon Slayer campaign, and I only succeeded because of the Explosion spell. I entered a town, learned Slow, and then Explosion disappeared:( (maybe someone knows where to find the removed spells:smile45: )
