Hm yes you're quite right, money isn't really a scarce ressource.
Maybe just having to pay to get to the content, with no gold inside. Or the "gambling" may be paying a sum and hoping to get it back with the content.
The main idea was essentially to find an alternate way of giving Lockpicking more credits without having to re-do anything in the world, as revisiting the map to add or modify locks really sounds like a big, edgy thing to do.
I completely agree the best of lockpicking comes when you can use it to bypass things, when it IS a real alternative. I mentioned FallOut 1 and the infamous locked door you could lockpick with the proper skill and bypass a big part of the game, this is good and satisfying design and it even kicks in in later playthroughs when you now know you could have done that right from the beginning.
It's just that I don't really have high hopes about that, as we are in Beta and not Alpha anymore and I don't really know if they would undertake such a task... But I like it more.
It's indeed a bit tricky when fights can bring such good XP and you don't want to avoid them though... And giving a succesfull lockpick an amount of xp equal to what you'd have got for the fights isn't a solution as people are just going to lockpick and then proceed on the normal path to get both rewards. Aaah, damn you, metagaming !
