Hello there!
this is a topic for all those poeple who don't know the tactic's yet.
in dragon soul are 8 bosses
[Morchok] [Warlord Zon'ozz] [Yor'sahj the Unsleeping] [Hagara the Stormbinder]
[Ultraxion] [Warmaster Blackhorn] [Spine of Deathwing] [Madness of Deathwing]
First boss you will face is [Morchok]...
a very easy fight tanks gotta focus [Crush Armor] its meant to stack till 3x maxx then the other tank will taunt the boss
for the dps and healers focus the [Resonating Crystal] when you get a beam on you. runn to the [Resonating Crystal]
a few time's 2 a 3 he will throw everyone to him self (holl raid) after that Runn and hide behind an pilar to avoid the AoE raid damage
Second boss is most likely [Warlord Zon'ozz] this boss will summon a [Disrupting Shadows] orb that need to bounce around like tennis most likely to play whit 5 - 3 - 3 - 3 (1 time you stack to 5 second till boss is death 3x) also after that stacks are reached the orb gotta hit the boss so next phase will start. in this phase stack all up together as close as you can... the boss will take addition damage in this Dark phase.
Third boss [Yor'sahj the Unsleeping] another pretty easy fight all you gotta do is focus a bit
this boss will summon ooze's 3 ooze's at a time u need to kill 1 of them in a prior of Purple [Shadowed Globule] » Green [Acidic Globule] » Yellow [Glowing Globule] ... when you killing purple and Green hits the boss Spread out only 4 yards of each other (just 1 step) all the others Stack up... at black use all your AoE cooldowns you got.
fourth boss [Hagara the Stormbinder] most easy boss after the first one... no dps race just focus and there is np at all... for the tanks this boss use alot of time's [Focused Assault] which are not interupt able... But... you can interupt it by moving away from the boss... so focus this tanks... for everyone els this guy got 2 major ability's 1 time he gets himself in a water shield and he will spawn 4 ice crystals which gotta dps down asap and summon's 4 ice walls who kill you instand when they hit you... so runn clockwise don't get hit by the wall and dps ice crystals... on the other phase he summon 1 air elemental take him down asap then stack on tank all together and runn clockwise to be able to dps the boss again...
