No. People just read/watched the tactics, and once you know what to do this raid is piss easy. I was watching movies on TV half the time while healing the raid.
I've cleared 6/9HC bosses today again (to roll coins) with another pug from LFR. We were 12 people who knew what we were doing.
The bigger the raid, the more chance you will fail, because retards without a clue join PUG raids and expect to be carried.
About gear - we were about 910+ ilv which almost everyone has nowadays.
I did go through a few "Mistress" LFR pugs that fell apart cause people had no idea what to do. Then just formed a fresh raid with people who knew tactics and cleared 6/9HC in under 2 hrs.
I find this raid easier than Nighthold Citadel. Easy tactics, fast fights, short instance overall. Though raid design and fights look pretty.
Update: couldn't sleep so i fired up wow and joined the first Maiden of Vigilance HC group from LFR. Killed her in 1 try. I spent 2 mins reading journal tactics. There is NOTHING hard about that fight at all. (switch sides / jump down with bombs). You people are either bad or over-dramatic. NH HC was harder.
And this is a first try on the Avatar with a random LFG pug:
Easy as hell, just a gear check for DPS. EDIT: killed him on 3rd Try. I dont get what all the fuss is about.
