The current procedure is as follows.
- click on create hero.
- select class
- check if you like the abilities.
- if you do not like the abilities.
- delete hero
and then it starts again at 1.
I wish they would optimize the whole thing a bit.
- click on create hero
- choose class
- directly see which skills and the option to recreate the same hero with gold or gems.
- And when you like the abilities press on KEEP HERO!
