I never got teleport spell and invisibility spell before mid to late game, and I still haven't gotten my sneak to 5 on even my rogue character. Maybe you should let the choice of skills and specializations be based on what you want for your characters, instead of based on min/maxing?
i want for my character to be as strong as possible
and most ppl want the same
so why not just make the maximum power not be a godlike power but just balanced?
