The Twilight Destroyer (10 player)

New Raid as of 3.3.5
3 Bosses, You need to defeat the 2 on the Side in order to fight the one in the back
Once all 3 are dead Halion flies down.

Trash is a bit interesting, Invokers need to be interupted or they AoE KnockBack the Raid, Commanders place a buff onto themselves and other mobs that increases damage done by 25% Per Friendly Target Within 8 yards, So it would seem logical to split the groups up as thin as possible (4 Mobs in the groups on 10 so you would probably want to split them up into 2 groups of 2)

Currently only tested the "Warborn" (Boss to the left)
He has a debuff that needs to for tanks to swap (The Debuff seems to be on himself)
And at about 30% he splits into 2. Due to Lag we wiped So thats all the info i have. :)

We already have people on our server asking for the achievement for this on the first week, don't ask why, but here's the cure to moron pug leaders again. Type this into any Chat log (after pressing Enter) and it should give you a spoof achievement, the date for this one is July 2nd 2010, which was Friday. You can altar the date where it says "1:7:2:10:" just replace that 2 with a similar number.

We all pay the same amount, we should all be allowed to play the same amount.

What works for us is to have second tank stay outside the whole time. It you have a Druid tank, It is very helpful. He can Brez and innervate someone who dies in phase 2. Its the most help, though, to be able to pick up boss before the other dps or healers pop out of the port before the tank. It also help healers with 1 less person to heal or get debuff. Also, The second tank doesnt have to worry about staying alive during phase 2. Second tank may have to be ready to pop CD's right off the start of phase 3. Due to lag, latency, or healer having to run to port from phase 2 may leave the second tank vulnerable for a few seconds.

Bring a shammy and bloodlust at phase 2 and it becomes a cake walk.
