This might be a noob question, but I just did all the bosses in LFR highmaul and only got these hyper augment runes? Are you supposed to use them for something to get loot or how does loot work?
What you should probably do with the augment runes is sell them on the AH. They go for a ton. Unless you are fairly hardcore and already using pots, food, and greater flasks they are not really for you.
