I really really like this fight for a few reasons

• Awareness of surroundings (forces all classes to actually look at the game, be aware of their surroundings and make a large effort to not stand in the shit that hurts)
• Situational awareness (watching grid to see if you're going to get a heal or need to pot, is that rogue running at me, where the hell can I stand to maximize dps but still land my required kick/CoT/CS)
• Self Sufficiency (I love love love the fight for this reason, and this reason above all else)  I ate nine envenoms over the course of attempts, and that again or more of divine wraths, random AoE's and my own lifetaps/reflective shielded dots.  I never died, honestly, unless I had just lifetapped and/or gotten caught in an aoe before a poison, I never needed heals.  My HS's sat unused for the first 3/4 of attempts because I simply didn't need more than drain life/death coil/or the fast reflexes of our healers.  This right here, this reason, is what will separate the good raiders from those you say "fuck, I want that guy on my wing when it's go time" 

This is the iron man contest of wow.  "do you have it in you to dps/heal/tank for fifteen minutes totally self aware/sufficient/sustained while contributing in a stellar manner"  This is the hard core.  Illidan to me, meh.  five stages, learn a phase, move on, new stage.  Illidari is "these are horrible things happening all over the place, can you adapt, survive and conquer".  We've had a pretty easy learning curve up until now, everyone has fights they're required to perform above standard at, but this fight requires EVERYONE to be THAT good. 

Don't be discouraged.  Don't blame healers.  Don't blame DPS. Don't Blame Tanks.  Wipes happen, what can YOU as an individual raider do to contribute more? this fight is about everything and nothing.  It centers around instances of individuality while operating in a hive environment.  You are a self aware Cog in the raid machine, are you honed to fit with the other pieces?
