Problem

Create & Customize: Create your own hero and choose between distinct skill trees

On the steam page of the game, under "features" I can read this line... right now though all I have seen is a predefined hero in the campaign mode and the ability to choose from a pool of pregenerated characters in skirmish mode.

I am obviously missing something here, but I'll definitely buy the game when I see how I can "create MY OWN hero"...
