Abomination Wing 1: Patchwerk

[Bastet]

Abilities:
Hatefull Strike - Base damage is 23K-29K physical damage, thankfully this is mitigated through high AC. The average hit is ~8000 damage on a fully buffed BWL/AQ40 geared tank in defensive stance. This ability is never used on the main tank; the ability will hit the 2nd highest on the threat meter within melee range of patchwerk (not the person with highest HP).
Normal hit with melee is ~2500.
Enrage - 7 minute timer. This will make short work of the raid.
 
Strategy:
Patchwerk is unique in many aspects, in that he will keep attacking the first target to aggro him until that target is dead. Then he proceeds from 1st->last to aggro him. Meaning if a hunter is used to pull, he must Feign Death and the MT must be the first to aggro him after this.
This also means that the raid is unable to get aggro from Patchwerk as long as the tank is alive. (NOTE: It has shown that it is possible for a player to pull aggro, but under most circumstances is it impossible to generate enough DPS to do so). This makes it possible for the raid to all out DPS. This is important, as Patchwerk has about 4,000,000 HP and a 7 minute enrage time limit (your raid needs ~9500 dps minimum to kill him in time).
The main part of the fight is to heal through his Hateful Strike ability; It works like this:

• At the start of the fight, the 3 closest people to Patchwerk other than the main tank get primed for Hateful Strikes. If a primed tank dies, it is unclear as to how another person gets re-primed.
• Hateful Strike hits the person in range that is primed with the most threat.
• Hateful strike hits for between 22100 and 29900 damage before mitigation (= avg 26000 non-mitigated damage). This means it is roughly 7500 average damage after mitigation on tier-2 warriors. The maximum hit will deal 29900*(damage modifier by armor); this means that, with 70% damage reduction, for example, a tank needs 29900*30%=8970 HP at all times.
• Hateful Strike can never crit or be a crushing blow.
• Hateful Strike hits roughly every 1.2 seconds
• Hateful Strike does NOT try to reapply upon a dodge/parry/miss. This is a common misconception. This means that dodge/parry is extremely important because it gives healers 1.2 more seconds to top off tanks.

This fight requires OTs to be buffed up fully, using Flasks of the Titans, Stoneshield Potions and the like.
It is viable to either use one, or numerous offtanks in the fight.
