The augment runes stack with everything, so if you're on a server with enough Mythic raiders you can sell them for stupid amounts of gold. Chaining heroic dungeons as a tank with the bonus up is a fantastic way to make gold right now. You get 150g directly for killing the bosses, can disenchant the items you get into 20 draenic dust which is another 150g, and can then sell the augment rune for 150-200g. That's 500g for a clear and if you're in mythic highmaul gear you can pretty much do each boss and all the trash leading up to it in a single pull.
