I've read this in a couple of different posts about different topics. One was saying that they could kill Garrosh on Heroic multiple times in the same raid lock-out (i.e. same week).
I just read the following from Arriaa on open raid:

575 is the minimum to sign up (with the unlimited coins + upgrades from frogs as well as being able to enter heroic multiple times per week AND be able to coin every boss this should not be difficult to achieve for anyone who really wants to join
Can anyone confirm this?

With 6.0, they changed the way personal-loot occurs. Thus, you can run Normal SoO 20 times, roll 20 times, and receive 20 times the opportunity of secrets/runestones. Now, although you will only get loot from the boss once per week, you can get runestones from the same boss 12 times per week. You can also roll on the same boss an infinite number of times each week.

If I understand it correctly: You can run SoO Heroic. Get a chance at loot dropping in the usual way. Use a coin and have another chance. Do that for all the bosses and clear the instance. Leave the group, join/make another group. No chance you will get an item in the usual way, however, you can roll on every boss for a chance at bonus drops, even Runestones/Sigils/Secrets!
I've been trying to figure out why they would take out the gaze of the black prince buff when they removed the valor grind. All players would be stuck at the same part trying to farm the last 32 items in a few weeks. I guess this is why
