In terms of storytelling and content accessibility, there isn't a real difficulty. The way we handled Ragnaros was kind of unique, but he's not the final boss of this expansion.

Your idea is quite contrary to our motivation for implementing multiple difficulties. We want as many people as possible to be able to experience the story, while still preserving many of the more prestigious rewards and achievements for those who complete Heroic difficulty.

We've updated our Trading Card Game art gallery to feature ten new pieces. Each image is taken directly from the official World of Warcraft Trading Card Game. Be sure to give a shout-out to your favorite pieces in the comments.

Having the LFR group size set at 25 allows for a more forgiving experience should errors be made by individual players - after all, we believe Raid Finder groups should be a fun way to experience raid content without feeling too punishing to new or inexperienced raiders.

In regards to the loot issues you mention, such as people winning the same item twice, we're working on a solution for this.

In regards to Ghostcrawler's recent blog Seeing the Forest for the Talent Trees, we'd just like to make a quick additional point about "bringing PvE and PvP closer"; When we say this, we're also talking about making the idea of having to collect separate gear for each less of an issue (like it became in Wrath of the Lich King). For those who are concerned about having to "grind" to get good enough PvP gear to even step into a Battleground, our intent is to make this less of an issue. We want PvE gear to be useful in PvP and vice versa, but neither should be quite as good as the other. You'll still be able to be viable either way. Meaning, if you want to go from your Raid into a Battleground for a bit, you won't necessarily need to swap gear, and if you go from PvP into a dungeon, people shouldn't get immediately incensed that you didn't change for the occasion.

While we would like to explore some options for adding more world PvP (because clearly many players keep asking for it) it would purely be optional. PvE players with no interest in PvP should be able to ignore it and vice versa. We just want to provide more opportunities for crossover (again for players who keep asking for it) than exist today.
