Please make it so you can't get Ley-Lines if you have no skills that use Mana. Please make it so you can't get both Dual-Wielding and Shields or Unarmed Combat. Please make it so you can't get more than two different melee weapon skills.
I dunno, it's not like you can't just mash the Random button again. I mean, if you're really going hardcore, you take what you get, right?
Exactly -- some people actually WANT the extra challenge. I know that early on, people were actually asking for the option to select fewer than seven skills. So the ability to actually take something useless as a skill is really a valuable part of the game to some. Taking that away just for a miniscule bit of convenience just doesn't make sense.
