Which mixed hero class of a particular race do you like?

In my opinion, the Archmage is cool... but overall, the Barbarian!

I don't remember Barbarians being available in the Haven castle. :)
But a fighter hero with upgraded life magic is incredibly powerful... I've created one myself. :)
I don't know how long it would take to defeat him...
Once, my friend and I had two such monsters meet... I don't remember exactly, but we fought for over half an hour. :)
