Normal Iron docks drops a significant amount of Iron Horde scrap. A profile that would clear up to 1st boss, run out, reset, could get quite a bit of scraps in a short amount of time.
You can get a lot more from the iron horde camp in Talador. Totally north, above frostwolf overlook. Also safer to do as you won't be running the same dungeon over and over, making it less suspicious imo.
