I only had one wipe in look for raid on each of the two characters I ran through it last week (my main and my primary alt). With my main, we wiped on the last of the first four bosses, when people didn't know to move from the moving ice spikes. With my alt, we wiped on the "ping pong" boss because people were attacking the ball and then not letting it hit the boss.

So I've found LFR to be very pain-free so far! Haven't tried normal yet - we didn't have enough guildies on last week to do our normal raiding (university finals and family commitments resulted in us not having enough raiders available last week).

Yeah, I think it's more a matter of LFR groups just being significantly more variable than your regular raid group; rather than difficulty mode balancing.

Sometimes you'll get into an LFR group that can't even get through the first trash, and then other times your LFR group will cut through all the bosses like a chainsaw through butter, and all points in between.

In a way, this is one of the things that I kind of like about LFR. With your regular raid group on normal/heroic mode, you know what to expect. But with LFR it's always a surprise.
