Nostalrius Begins - Quality wow vanilla realm (1.12)

In deadmines, just before the forge goblin area, there are a tin vein and a cooper vein that spawn every minuto or so, it give from 1 to 5 ores, and so aswell as the box of assorted parts, thats a huge problem that could imbalance the economy in the game

I, myself, could grind 22 cooper ore in 10 minutes! and around 30 silver in the same amount after my group cleared the area, its not a lot, but in this populated server is a huge amount, specially for engineers, they can save lots of cooper whit the boxes, and still have plenty cooper, i believe 2 or 3 hours would be more than enough to give u plenty of maths, sup an items for it, pls check it

There were such veins on retail too. You could find such veins in world too but it was VERY rare. I don't think it's a bug to be honest but can't be sure. 22 copper in 10 minutes is nothing but right now low level zones are overpopulated so you can't farm copper that good.
