I think perhaps this should be a message to Blizzard that despite having all of the in game warnings that they provided, some of these encounters have gone beyond a 'challenge' into 'RNG and latency issue hell' by having so many fights be -so- dependent upon moving at just the right times or you die. A guild full of very competent people smashing up against a single mechanic, on a fight that might not even be a wing boss, despite knowing and understanding the mechanic and yet still not being able to get that last bit of last second warning or what have you because of how timing dependent so many fights are, is making it a whole lot less challenging and more aggravating and a risk of driving away players. I think the fact that so few raids have managed to down the LK is a pretty good example of this....Blizzard is treading on having things be 'too' hard thanks to their mechanics and removing that accessibility they've been trying so hard to insert into the game.

AVR was alleviating that problem that Blizzard seems to be trying to take care of not with making the fights just a touch less timing dependent or more latency friendly, instead Blizzard throws a power buff at it. Ramping up your players so that their dps becomes so big that it makes the mechanics not a factor is a bandaid on a potentially huge problem. If the fights weren't so complex in the half a dozen or a dozen things you need to be aware of at any given time, ICC wouldn't have needed the damage buff at all.
