After the NDA for World of Warcraft: Cataclysm was lifted yesterday I was able to look at some of the new loot that would be available for leveling and the initial 5 man dungeons. Let me recall the first words out of my mouth:
Blizzard recently announced that they would be combining the raid lockouts for 10 and 25 mans, in addition to increasing the difficulty of the 10 mans so they could justify giving it the same loot as the 25 man encounters (though, not as many pieces-per-player obviously). Within hours of being announced, the thread on the Cataclysm forums was full of a few hundred pages of discussion and flaming regarding the issue. While this is by no means an in-depth exploration, which I will save for later, this is an initial reaction.
