Well then, I see absolutely no problem at all. You still have to complete the mini-game, and you can't spam the force lock button without consequence like you could in Oblivion using the Skeleton Key. Lockpicking perks are very valid, unless I'm just missing something.
The skeleton key can't make you undetectable while lockpicking, either. With the perks, you can open doors right in front of guards and they won't blink an eye, unless I've drastically misread that perk.
na its unlimited. always was. wait a couple days and !tada! money to buy your junk.
...I'm still getting the speech perks. I don't want to have to run out and wait for three days, and being able to invest in shops and obtain new fences sounds cool. Besides, I'm playing as a charismatic character, so having those perks helps me feel charismatic.
