A "New Game+" option that makes a solo play experience more tolerable. Such as making you unable to take companions, but also gives you immunity to hard CC's like paralyze and petrify. They can still be detrimental in some way, just not a hard CC making you dead the instant a 10 sec petrify lands.
Well... there's already the Bareth's Blessing New Game+. That might cover it.
C'mon guys, these ideas are too vanilla. The titles says CRAZY ideas that you will most likely NOT get.
