Phase one(the most important phase,you may have a possibility of 70%to success if transit to p2 perfectly)

　　
 Now there're two popular method,the whole raid's positioning,or most of people stand at doorway while tank pulls boss in and out of house.the first one requires a higher power of  observation and reaction.so we choose another one,to reduse the chance of extra mobs

　
 We require tanks to pull the boss in at 40%(May necessary to go all round in circles for some inadequacy position of green cloud or DPS's fail of immediate stop),DPS standing out of the door need to stop damaging at 30%(Sometimes it's hard to stop ,so tanks need to pull the boss out of their distance   xD)in this way,mobs may have only 10%-15% health when taken to the position of sara,arrange 4 distant damager for them .

　　
 12%-15% health can be damaged by each of the mob,so we need about 8 mobs to pass P,however,the mobs created at an increasing speed,there may 3 mobs at one time when the 6th one created,and there may be 12 or 13 mobs when the 8th was killed if we just follow blz's method of creating mobs.generally speaking,failure was determined when there'r 2 mob for p2.

 However,dps are spare for 1-5,so we create 2  mobs ourselves by stamp,on the green cloud,so what we need to kill was only the 6th one blz set for us.when the creation was not so fast.

　
 So,we basically can transit to p2 perfectly(with few mobs on the ground that can be killed before tentacle appear)the occation of stamp the cloud is at the start of the battle and when the first mob been killed,Let cat druid change into bear or dk tank the separate mob if there are three on the ground,their dmg are very low.

 For paladins,it's wise to use bop at the very start or it'll directly buff on the mobs after mc.and it's almost cooldown at p2 so you can help somebody caught by the tentacle with it.
　
 A macro-instruction for you,"/cancelaura flash freeze"one of the 4defender may resurrect you and freeze you for 10s,and this marco can help you cancel the freezing state if you were healed.

　
 P2(you may have a possibility of 95%to success if transit to p3 perfectly)
　　
 The big tentacle can decrease damage,one by 20%,at most 4 tentacles,the middle sized ones can bind players,(can be cancelled by ice block or bop)
　
 tentacle would be created 5s after p2 boss refreshed,DPS kill the tentacle,then divide the work.bigger tentacle for ranged units and smaller tentacle for melee unit.we need melees  help people outside to kill small tentacles and save people by killing middle tentacle near the smaller ones.

 At p2,the time between boss appear and the first gate appear is 1 min,we brought 9 melees in so ti's easy to kill 2 small tentacles and millde sized tentacles.melees should better waiting at the gate 5s before it appears
　
 The faster we killed inner tentacles,the more time we get for DPS outside,we can provide about 40s for outside and the outside was all clear when we came out.the time from melees came out of the gate to the next door's appear was 20-25,so calculate the time and positioning before gate
　　
 The tentacle outside should been killed all by range DPSers,the biggest the first,epsecially when all the tentacles were rooted,Save is not necessary if someone was caught by tentacles,heal him or bop on him,almost all the dpser can deal with it,except hunters and rogues.
　
 It's the time for the middle and small ones.tentacles may easily caught  the meleesthe time before they enter the gate.(don't care about it,what you need to do is killing tentacles)healing him and ranges could offer some help if possible,melees even can enter the door if enough time left.For range units,don't care about melees if it's too far away and focusing on big tentacles.if the small tentacles are out of distance, left it to the melees coming out of gate ,20s is enough .
　
 Tanks need to approach the big tentacle to eliminate debuff cause by big tentacle.but the single attack may cause big tentacle of damage increasing.99times plus at most.And tank may killed by it if it has been added 50 times or more.so,all the range units should stop for a global cooldown to fade the buff away.then tank can came in to cancel the debuff of 20 dmg decrease

 To circling like this for 3 times,we can enter the p3,It suggested to use heroism at the first time melees enter the brain,don't use it at the room but the way to it,or people outside cannot share its impact
　　
 The only thing we need to mentioned is our sensible power,because our melees are always stays away from ranges.we're at the place of smalltentacles.so if the brain links ranges and melees,the melees should come toward ranges ,the doors are everywhere
　　
 In this way,melees can dps and positioning,ranges kills tentacles.Melees need to dps the tentacles with skeletons at the back to prevent from receive much rays and lower the sensibility power.and it also can save time to replenish sensibility
　
 A group of melees can be arranged for tentacles.or  let melees with lower sensiblilty to recovered outside advanced.It need raidleader to command.transit to p3 if possible
 P3　　
 Now there're several methods,we choose the two point positioning,melees for the boss,casters to kill the mobs with boss backward.hunters stands with healer.tanks pull the mobs to the melees scope so casters can get away from rays.AOE by melees can also help casters.
　　
 Melees and hunters need to turned back for 4s in case of rays.And recovery was needed for sensibility.healers cast spells backward the boss,that's ez....
　
 What this phase tests was the reaction of tanks.to pull the mobs as soon as it get out.Then ranges need to kill them in time,and cut the healing skill pf mobs.Make sure that there're only 1deadly mobs and a newly-freshed.then the boss was done.
　
 Line-up assortment:2 tanks 5healer 9melees 9ranges.May 4 healers if they're powerful enough,there's nothing to do on p1 and p2,1healer for a healer's enough in p3.
　　
　
 P.S.there're 3 scenes when melees enter the gate at p3
the doorway of red dragon and stormwind ,need 2 group for both side,walk a semicircle and turns back directly can save a lot of time.the third one is not so easy to cope with.3groups for 3crowds of mobs.and help others when your task has been done.
　
 P.S.2.the brain links disappear after you enter the door,so it's lucky if melees was linked at the time they enter the door,and the links means nothing
