Not using in P1 may mean one more set of adds, but that's no biggie. Now, the main part of P3 is not freaking out, this leads to bad weapon placement and bad MC handeling. First of all make sure you have all Healer and Tank CD's up for this one. I suggest having boss + tank + melee in the middle and ranged as close as possible to a wall. Desecrate comes in, they move into melee, handle MC (a tip here is having people going on the people in their group), then move out to the wall again and await whirlwind.
You should aim for having the boss go down before a third whirlwind, so whatever Cooldown rotation you have for these, make sure that the ones who are usually used for number 3 are used on 1 and 2 aswell. Suggestion is that you use one dk shield for each of the two. Devotion aura and Pala healer CD's on the first one, tranq on the second one (druid might have to get hit by 1 add spawn here, consider moving or have pala use sacrifice on him). Make sure ranged stay as close to the wall during the whirlwind as to place the desecrate nicely, then stack up on boss again to deal with MC's. Ranged goes back to the wall after, spreads for whirlwind, place desecrate, stack up for MC, finish them off.
At this point the boss should be close to dead so just stack now and NUKE THE LIVING SHIT OUT OF THE BOSS! If you reach a third whirlwind, have people use everything defensive they have, and make sure to spread out still, and nuke even more on boss. If the boss isn't dead by now your dps need to pull it togheter, simple as that.
EDIT: Looking at your dps uptime i do wonder what you guys are doing wrong. You have 1 attempt that last for 8+ min where everyone is on around 95% uptime, the rest of the time you have plenty of people around 91-92%. This is not good. In my guild averaged 97,61% uptime on our last kill. Adding togheter two of your guys tries, you had 92,16%. Quick math here, we had 5,45% more uptime. Took your dps and divided by 100 to find what 1% of your dps was, and it was close to 15 . Take that number times 5,45 (the % uptime in differnce from us and you guys and the number you should be aiming for) it becomes 82,5k. So, with your low uptime you are loosing about 80k dps EACH SECOND! For the duration of the fight, which in most cases are around 9 and a half minute, you could be getting an extra 47 MILLION dmg into the boss with having better uptime.
How to fix this uptime issue? Not sure really, maybe someone better at reading logs than me can find out or you just have to tell your dps to focus more.
