My fully leveled security person who like for you to be able to break that door down as long as i can stab a dragon in the eye with a lock pick.
If you remove the utility of skills because you do not want to take them you make them pointless
So the question stands, if you can replace lockpick with combat prowess can i replace combat prowess with lockpick?
Counter arguments:
1:
Thief types get lockpicks.
Mage types get an alteration effect that unlocks things.
Warrior types get... nothing.
2:
There's still doors that cannot be unlocked by any means but finding the actual keys, making the entire lockpicking system pointless since the doors you'd want to do it to the most cannot be picked.
Of course, big and sturdy doors can't be broken down at all (sturdy full steel or thick hardwood doors). However, http://img518.imageshack.us/img518/4459/cave03aftercf8.jpg should
not be invulnerable to any kind of violence, be it forcing locks, breaking down the door, burning it or whatever, it's just pretty ridiculous - Especially when the rest of the game is usually so believable.
As for combat: Thief types get sneak attack bonusses, are usually far better at range due to their focus on agility and speed making them able to kite a lot (and thus avoid damage alltogether), can stay hidden as long as they please without even using magic - For a warrior type character which is by definition only good at close combat (heavy focus on strength and endurance out of necessity), being able to put that strength to use to break down the occasional thin wooden door doesn't seem like much of a stretch to me.
By the way, personally i prefer the stealthy play, at least in Oblivion. This thread mostly came from my experience in Morrowind, where my fully Daedric equipped warrior priest with 495 strength (thank you corprus bug) was unable to even put a single scratch on http://1.bp.blogspot.com/_IihlvQBAqf0/TU8pgDj4z-I/AAAAAAAAAP0/edBlTqQYWUw/s1600/Morrowind+2011-02-06+17-16-59-70.jpg, and it really made me wonder why in Morrowind this was an unpenetrable barrier whereas in Daggerfall, a game 6 years older than Morrowind, they had such a simple thing working.
