I've been in 13 LFR's for SoO this week, none of them got past the first boss. Most of them continuously wiped on trash, and of the three groups that did make it to the boss, they never got past the first phase. I definitely know that I'm not the only other player suffering from these failed groups, I was in a conversation with another raider who was trying to just get a 2h weapon from the boss, he was in a dozen other LFR groups that all died on first boss too, and he still hasn't gotten a chance to get his weapon. All of this time waiting to get into SoO for two hours, then waiting another hour to finally figure out that they won't ever get past the first boss before requeuing. It's really, really aggravating.
P.S: I've spent over a thousand gold on repairs, without any loot to show for it. Lesson learned: never LFR on weekends.
