I was listening to one of the main WoW podcasts, and the host and guests were saying that LFR is beyond stupidly easy.... that healers almost didn't have to heal, and that nobody died... in fact, the host said he saw one character running into walls for the entire LFR boss fights, and it just didn't matter.
I never even did LFR ever before because I played on a laptop, and it just could not keep up.... but now I have a very nice desktop, and want to start with LFR.... but not having any LFR experience, I am kind of apprehensive.
I did do ( 2 ) 5 main dungeons so far. It went OK, I guess.... I died 2x from being blown of the top in skyreach, and then I realized I was not fighting the wind the way I should have.... ( I didn't see how the others did it, or I would have followed them ). And I died once on the one with the train on the end boss. But our tank was from my guild, and he was already geared for heroics, so I likely may have died more often.
