I don't know. I just feel that it's weird how lockpicking and pickpocketing are separate skills. I never really picked pockets in oblivion. If I wanted to steal something, I could just kill the guy with sneak attack and take everything.
I thought lockpicking was a completely useless skill in oblivion since we can pick the hardest lock at early levels. You can get a daedric artifact that's an indestructible lockpick. Maybe if they have lockpick like they did in fallout, it might be more important since picking locks is useful in quests and you can't just lock pick anything if you're skill is too low.
I guess they could make those skills more important than they seem with some perks. Maybe I'm not much of a stealth guy. I feel like those skills are too trivial to be on its own. It could merge with sneak or make a new skill called 'hand-dexterity' which would include lockpicking, pickpocketing and maybe even thowing weapons and hand-to-hand. I guess lockpicking was always a separate skill in TES games (as security) but did we have to take pick-pocketing out of sneak? It just gives me an impression that they just took it out of Sneak just to have 6 skills for each set of combat, magic and stealth.
