Apparently the strategy for yogg involves heavy warlock stacking because of the nature of lock dps in p3 -> Drain Soul channelling doesnt require you to face the boss. lolololol.
Taken from Ensidia forums:
1 mage (there only for p2 outside decurse)
SP/rogue(major AOEer to suppress Shadow beacon HOt healing, and AOE down IG)
warlock(major dps on yogg, drain soul can get as high as 16k-18k per tick)
2 hunter and 3 tanks (the most tactical persons, that when beacon comes sperate them and then get them together for AOE)(3-5 beacons)
1 disc priest and 2 pally for 1 tank each , and healing druid for mobile healing.
timewise, there is only 3 beacons for you to down the yogg, otherwise you will get overwhelmed
for beacon, when it comes, the move of hunter/tanks are crucial, and any mistake is wipe (there are randomness, that IG with beacon may be clamped to one tank, which is wipe)
everyone dps must have the ability to do 5.5k-7.5k dps even you have 1/3 of time not facing boss.
because drain soul and no need to face yogg and good aoe, the more warlock , the better, 10 warlocks make it very trivial.
