Dear VBN, why haven't you paid attention to heroes with "innate" earth, air, fire, and water magic? Or is it a secret to you that, with a certain "setup," you might not even get the "right" secondary skill.
Or do you think such heroes are useless?!
There's a great map called First Blad. It really needs a hero with scouting skills.
If you're going to do something, do it all the way, my friend, finish it properly, or don't do it at all.
And you should have named the topic "heroes with a specific skill and secondary ability," since that's what you're talking about.

Sincerely
