Now this isn't some huge game changing suggestions but, I was thinking that maybe the 'Thief' perk should give +2 pickpocket instead of lockpicking.
For a few reasons. Firstly, I think it's more thief like, pickpocket over lockpicking. Secondly, there is already a perk for picking locks that gives +3 to the skill. It would be nice to see a variety of skills.
Thats it really.
The value of Thief is that it offers a bonus to stealth. There's already one that offers +3 pick pocket too. Thief also lacks a Pure Bonus.
Maybe +1 Locks, +1 Pockets, +1 H/MS, becoming +2 H/MS as a pure bonus?
