Overview of each Boss:
The basis of this fight is that you need to have at least 1 person on each of the platforms or they throw up a zonewide debuff that will screw you over.
Rohash (The Eastern One) is tankable by a ranged dps, and is a real pain to attack with melees as there are 3 tornados flying around that platform that do high damage, pretty much unhealable. This means you need to have one healer and one dpser over there (10 man), and 2 healers 1 dpser (25 man). He also has an ability that throws everyone on that platform in the air he uses when he gets to 100% energy. This means that the DPSer or Healer needs to have levitate/slow fall, so one of them has to be either a mage or priest. He also does an ability called Winds of Change, which is a C'thun beam style ability, but if you get hit by it you take a lot of damage + get knocked off the platform (and get carried back up by the winds but you cant heal/dps at that time and still take damage so will likely die). This ability is very hard to see so be very careful! His normal attack is a weak ranged attack with a 1.5 to 2 second cast time, easily tankable by any ranged dps. Also, if nobody is on the platform the entire raid gets silenced as well as a stacking nature damage DoT, and this will trigger if you all get knocked off.
Anshal (The Western One) You should start the fight with one tank and one healer and one dps with him (10 man), two healers one tank and 3 AoE dps (25 man). The tank should focus dpsing down the adds, as they dont have much HP, and make sure the boss and none of the adds are in the void zone he spawns (Soothing Breeze).
When he gets full energy he casts Zephyr. This is a channeled spell similar to tranquility, healing the boss and all adds and giving them all a stacking buff increasing damage by a large amount. Until the buff fades the boss will REALLY hit hard, so make sure to get cooldowns on the tank.
Nezir (The Northern One) should also start the fight with one tank and one healer (10 man), one tank and two healers (25 man). This guy has a lot more health than the other two in both difficulties, so the majority of your time will be spent here (unless you are assigned full time to somewhere else). This boss does a stacking debuff increasing frost damage taken by 10% each stack, as well as a frost damage aura, so you will need your tank/healer(s) assigned here to switch with the tank/healer(s) assigned to Anshal (western one) after around 3-4 stacks. This is done by both teams going and jumping at the same time, this results in no debuff because it takes a good few seconds with nobody on the platform for those to take effect, and makes the swaps as pain free as possible.
This guy's main ability is a frontal cone of frost damage. It's high damage so make sure it's facing away from any DPSers. He also does frost patches on the ground quite often which provide a slow and high DoT to those foolish enough to stay in it.
When this guy gets full energy he does a 15 second "Sleet Storm" which is a powerful frost damage DoT, also affected by the stacking debuff. Just power-heal through it and it will be fine.
The Fight:
Basically you split your raid into the appropriate groups and you are able to go to your respective platforms before you engage as well, their aggro radius is quite small. You will need to use slightly different tactics on 10 to 25 man, so I'll separate them below. These are the general areas that overlap on both difficulties:
All 3 of them need to die within 60 seconds of eachother, once one "dies" it channels a 60 second long buff called "Gather Power". If you do let them cast then it will be a wipe, so make sure you kill them within 60 seconds!
Another thing to watch out for is that when they get 100 energy and do their ultimate attacks, the wind tunnels you use to travel from platform to platform on are disabled for the 15-20 seconds they have their abilities up. So be careful with jumping during those times!
So you have 1 tank, 1 healer, 1 dps go to Anshal (Nature guy, west platform) and 1 tank, 1 healer go to Nezir (Frost guy, north platform). The rest of your raid (4 dps, 1 healer) will head to Rohash (Wind guy, east platform). On the pull you have all dps nuke down Rohash to around 50% health, then all but the assigned 1 dps and 1 healer jump over to Nezir (Northern platform). At about the same time you will be doing your first tank swap to reset the stacks (if you have good dps).
The 3 dps that go to Nezir will dps him down to about 20% while the dps that remained with Rohash will continue nuking him but not killing, of course. Once Nezir is on 20%, you jump over to Anshal (about the same time as the next tank swap if you have good dps) and kill him. Once Anshal dies, Rohash will be on 5-10%, and then all dps from Anshal's platform (plus the tank and healer) can jump over to Nezir and finish it off about the same time as the single DPS finishes off Rohash.
Overall a simple fight, they die very fast as they have low health, once you know their abilities and what to look out for then it's very easy to counter/avoid everything.
