Allright. We attempted Sartharion +2D last night (tenebron+vesperon). You can see our wws here: http://wowwebstats.com/rcrpmaoncys4k (yeah, that's alot of wipes!)
Short summary. We died because of 2-3 reasons:
1. People doing really stupid stuff
2. Tenebron every now and then turns around, and the tank has difficulties getting him into position again, and the his breath kills the raid.
3. The second wave of whelps spawn before Tenebron is dead, owning our whelp/fire elemental tank.
Short summary from what we found out to be most efficient:
Not dpsing the fire elementals, only when enraged we assigned one ranged to kill them (elemental shaman). Not DPSing any whelps that spawned from portal.
We had an unholy DK in mediocre tanking gear tank tenebron, a prot paladin tanking all adds (decent gear) and a tank specced druid for sartharion (decent gear)
When stuff worked fine, we killed tenebron right before vesperon landed (heroism required from this) and when we did not have heroism we most often could not kill tenebron before his 2nd wave of whelps spawned and owned our adds tank because of too much armor reduction.
We had 2 healers, 1 disc priest and 1 resto druid. (im disc priest). Tbh druid tank didn't take alot of damage at all. However when people actually didn't mess up it got really intense healing the adds tank after a while.
Our plan was to kill tenebron, then AE whelps (hopefully before vesperon lands). It wasn't possible though, I got the feeling heroism was required in order to do this, but ppl messed up when we had heroism so those tries weren't as good as they could have been. We tanked the dragons according to the strats4u sarth3d guide/video.
My questions:
2. Why does he do this?
3. Are there anyone with "hard numbers" on raid dps that is required to beat sarth 2D and sarth 3D? Do anyone have a WWS from a succesful 2D and 3D kill? I have been looking but haven't found any.
3.1. Will whepls stop spawning from the portal when tenebron dies, or will the 2nd wave come anyway? If he can't use ability "hatch eggs" he shouldn't be able to ... umm... hatch them?
