Secondary skills in Heroes 3.

Hmm... a second hero?! Level up a second hero?!?!? Not level up Wisdom?!?!? The only thing additional heroes need is +resources and Economy. Maybe also Navigation + Scouting + Logistics, but that would only result in a scout who can transport an army from the castle. Making two combat (meaning attacking) heroes is, in my opinion, stupid. Unless that's what was meant...

Stupid? Really? And what will you do with your one hero on a large map when weak enemy heroes attack you from all sides, and you have several cities that need to be defended? And what will you do with your weak secondary hero? My father, for example, plays Heroes very well and has often scolded me when he saw that I was doing everything with one hero. Of course, it also depends on the play style, but don't jump to conclusions.
