This is the first ever tier where I - and my raiding group - been heroic geared for new content.
I'm not sure whether it's because of that that my raid is breezing through the first few bosses or Blizz is just making content easier in general, but it's a completely novel experience for me to be so far into a raid dungeon this early.
In 10m, we got up to the 7th boss (Kor'kron Dark Shaman) in the first week of raiding... and even then, it doesn't look like too difficult a fight. We just ran out of time!
I think it's a lot better being ahead of the curve... you don't run into fights where you're lacking on DPS/heals - a source of frustration for everyone because there are usually people who "carry" the raid, whether it be gear or skill. It's never fun waiting for people to catch up.
In our case, even if there are some better geared (or better skilled!) than others, it's not enough of a gap to significantly slow progression. Woot for the new and improved raiding experience! :)
(On the other hand, I've suddenly discovered I have much less patience for LFR... was considering not bothering with it, but I feel obliged for the chance at loot :P)
