Ah, you're discussing the heroes based on their abilities...
And I'll be describing them based on their moral qualities. :)
Most of all, I naturally like Agrael. He fell in love with Isabel (at least someone has feelings), deceived Kha-Beleth, and turned into a Dark Elf...
Next on the list is Wulstan. He's funny, and when he's with Duncan, it's even funnier...
And I also really liked Nicholas's mother, with whom Markel talked at the beginning of the campaign. "Wouldn't you like to see Claw again?"
