Campaign Mode/Individual Characters

I thought a bit about what is missing in DD yet and I found one thing:
I always play with the bloodmage or the assassin, but never with MY hero.
I would love to be able to choose a name/portrait in the beginning and start with a low tier hero without any abilities, that could grow between different missions.
Maybe every different dungeon he wins, I can pick whether to increase his attackpower/mana points/... and on every third different dungeon win you get to pick one ability (maybe presented in a mission like the class quests, that you have to beat to get your ability), so in the end you get a bad ass character that you like to play and that is your own
