Looking to get your raid on when Cataclysm finally lands? There are a few very serious major changes incoming that will rock your Vanilla/BC/Wrath world that may lead to the end of raiding and dungeons as we know them…or maybe it won’t make much difference to you.

All in all, this is going to be a lot to swallow for most players, and will represent some serious and significant changes to the way they raid. Some of the highlights?

First of all, 10-man and 25-man raids will drop the same loot, just in different quantities – that means 25-man raids won’t get higher item-level gear like they currently do – a lot of people have been fighting this point on both sides, and it looks like while at first Blizzard was coming down on the side of the people who favored better gear for 25-man raids, they’ve reversed course a bit.

Second, 10-man and 25-man raids will share the same lockouts. That means a 10-man group gets the same amount of time to complete a dungeon as a 25-man group. Yowch. That would be a problem if not for the fact that also announced is the fact that 10-and-25-man bosses will be very similar in difficulty, and not the pretty big difference they are today.

Blizzard also has some plans to change up the way raids are done, and create shorter raids with fewer bosses (much like the heroic Onyxia and Sarth runs) that are still difficult enough to accomodate a large number of people, but that just have fewer bosses.

Like I said, all of this is still up in the air, and Blizzard reserves the right to change all of it, but if anything I can see it’s a pretty big leveling of the playing field between 10-man guilds and 25-man guilds and the dungeons they run. If anything, it may lend itself to the thought that Blizzard’s noticed that 10-man runs are mostly guild runs with tight social groups, and 25-man runs are largely pugs that are done for efficiency and loot. Interesting.

What do you think? Will the new announcements impact you at all?
