I think rogues should be able to craft lockpicks as they are the consumables for their class. Using bits of metal or even animatron parts!
crafting lockpicks
Or nails from chairs! Heaven knows there are enough broken chairs in Lower to create an army of lockpick monsters.
Or if a new crafting reagent isn't wanted. Simply allow rogues a once a day ability of Craft Pick that doesn't require any reagents. The type of pick they get is based off their lock picking skill. Non dropable maybe.
I think rogues should find their lockpicks on quests or buy them from merchants.
Not a bad suggestion, but sounds like a lot of work from our end for an extremely minor feature. There are many other things that we'd prefer to do that would make a bigger impact on players and the gameworld.
You guys have a list of important things you have do, don't you? On CoA it was located at the celestial crossroads between Gehenna and Elysium. Hmm.... I want to see this list.
I do like this suggestion, if it were doable. If not, meh.
