Let me ask you this genius, lets say you have a choice between a skill devoted purely to opening locks and a skill that includes the spell to open locks as well as many other spells, from a purely tactical point of view which skill do you think would be the smarter skill to take?
Now lets break it down even further, in order to pick locks with the skill devoted purely to picking locks you need to carry around lockpicks and succeed at a minigame where if you fail eats away at your supply of lockpicks, however in order to open locks with the magic school that contains not only open lock spells but many other useful spells you merely have to cast the spell and off pops the lock costing the player nothing but sweet regeneratable mana, does that really seem "Balanced" to you?
Now if you want an open lock spell then the construction kit will be released soon and you can mod in any exploits you like, however open lock was removed from the vanilla game for a reason and that reason is that the open lock spell makes the whole lockpicking skill superfluous, you may not agree however this is not an opinion but an unadvlterated fact.
Let me ask you this if you have two routes to get home one takes 20 minutes the other 30 minutes. Tomorrow they close a bunch of roads and you only have one route to get home the 30 minute route. Did that route become any faster now that they removed the 20 minute route or is it still the same 30 minute route?
To put it more simply, removing the open lock spell did nothing to make the open lock skill any better, it is still the same pile of svck it was before except this time you just don't have a spell option around it. So they kept something svcky, made somethings else svck and this is somehow the right choice due to balance?
You might want to rethink this balance issue a bit before you make it the go to excuse for making the game worse.
If bethesda had competent game designers instead of just a pile of awesome world designers and svcktasitc game designers they would have you know made open lock a better skill in order to make it better, and not made other things worse so it looked better in comparison while still actually svcking.
