New difficulty settings for the campaign

Hi,
Game is amazing but campaign could be a bit too easy.
It would be nice to be able to enter extra difficulty option in it (while staying in the same Ladder).
I understand you could easily skip the campaign but for thoses that did want to play it and build the character/test the skills doing so an extra level of difficulty with stepper progression would be appreciated so there is more progression toward endgame difficulty.
Thanks.
