I've always been curious how this should be handled. As a healer I don't keep up with DPS theorycrafting too much other than to know rotations so spot when someone isn't doing what they should be.
However, my guild is currently stuck on Heroic Horridon and when comparing our logs other guilds, it seems like we're fairly low on the DPS numbers for a guild in Heroics. Our top DPS on Horridon is usually doing at max 150k and on average our DPS do about 130k. Comparing this to other guilds(even guilds on my server that we are ahead of in progression) that seems fairly low.
Now my reasoning behind this is that my guild focus fires down the big adds on every door before worrying about cleaning up the small adds. Basically that means next to no AoE minus AoE that is included in single target rotations and small amounts of actual AoE as we're cleaning up the smaller adds.
A good example of this in my opinion is that our Survival Hunter does about 140k on the fight fairly consistently compared to another hunter on server in about the same gear level doing over 200k.
So anyway, my question here is on a fight like Horridon where there are priority targets that need to die ASAP, should AoE rotations still be used? Or should the adds be burned down one by one?

Our Transmogrification guides have been updated for Patch 5.2. This means that all the new items from Patch 5.2 have been added. We also added the Tier 15 and Arena Season 13 sets, as well as the Challenge Mode armors. Finally, Arena Season 9, 10, 11, and 12 sets are now obtained slightly differently than before, so the guides were updated to reflect that.
For our Patch 5.4 update, we will work on getting our model screenshots from the WoW Model Viewer, so that we can give you the option to display the models the way they look for female characters as well as for characters of all possible races. We may even be able to show items the way they will look in Shadowform.
So, stay tuned ;)

We have just released our first ever video guide for a raid boss:


Naturally, any feedback will be greatly appreciated!
Also, all our class guides have been updated for Patch 5.2. There may still be a few stat priorities to tweak, but we will be working on them in the next few days. Our BiS listings are not updated yet, but that will come soon.

We have just released our guide for the Council of Elders, the third boss encounter of the Throne of Thunder.
Also, Priest and Warrior guides have been updated for Patch 5.2 (with the exception of the gear pages, which will be updated later on).

This thread is for comments about our Horridon encounter guide.
