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

They are a kind of phenomenon among mages :) And you are right - they are unlikely to be worse than a warrior, because their specialization is excellent and their skills are suitable for any situation... the only thing that bothers me is the prevalence of increasing magical power/knowledge among mages, at the expense of attack/defense. With Dessa and Gundula, I believe there are no differences from the other mages...
