I'd love to write something up that's more comprehensive, but for now I'll just list a couple of ways they've been nerfed since the class was redone into paths.

- Used to be able to lead with weapontrip.
- Advanced lockpicking no longer opens what it used to.
- People/mobs now wake up and attack when you try to steal even after you knock them out
- Gentle walk used to be more powerful (Yes, it was probably not as intended)
- The best thief edge (DV) is just about unobtainable*

*1500 IMM XP. as a prereq. for 10 thief points. That will buy you shield block if you want it. How many hours are people usually at when they hit 1500 IMM xp if ever? Since we don't know how many edge points it takes, that means no edges until you get it. I had a thief with 2xDV years ago. Now, I assume it doesn't exist.

I know there have been others, but I'd have to dig to find out.
