I see your suggestion to just remove Burglary, Sancta. I just think once I start doing that, I might as well revamp the whole list because just getting rid of one Skill and splitting it up as Trappings or Stunts for other skills sounds like a bandaid. Giving Burglary pickpocketing as a Trapping is also a bandaid solution, but of the two I think it's an easier bandaid. If I'm going for something harder, I might as well go all the way and fix the Skill in total.
Does that make sense?
I applaud your revised Skill set by the way, that's way more work than I have the time for.
