There is one chest in Hallowfall that has a great text if you are a rogue, something to the effect of the key is missing, but you’re a rogue, you don’t need a key.
And it lets you open the chest when other classes have to look for the corpse somewhere down below.
It would be nice to be relevant, I know in Stormwind some NPC locksmiths complain about not being needed any more…
I am familiar with that chest and to be fair. The key is on the ground 70 feet below it down near the water. I could understand it being more frustrating if the key were lost somewhere in the zone and you needed an add-on to find it. But To me at least one chest in one zone is not very flavorful 
I got really good tips unlocking boxes back then, miss it…/sigh
I agree. Now all you need is a mechagnome or blacksmithing.
Oh I agree completely, but it was a nice touch at least.
Wish there was more of that sort of thing.
I used my free boosts on rogues specifically to open lock boxes.
I’m just annoyed that I have a kit that revolves around picking locks and pockets, and I’m not allowed to use it to solve quests that revolve around unlocking things or taking them from people.
