Achievements can now be gained as a Guild in the upcoming Cataclysm expansion. They have given more motivation for guilds to progress and conquer goals together. Every guild member will have their role to play in leveling their respective guild and unlocking achievements.

Guilds can level up to Level 20 (not concrete yet though) which experience can be obtained via members leveling, reputation, BG wins, Arena wins, profession ranks and boss kills which requires 75% dungeon/raid member in the party or raid.

The whole idea to leveling your guild is to obtain Talent points for each level which can be spent on your Guild's talent tree. Each upgrade or points taken will effect every single Guild member such as cheaper repair costs which is very cool in my opinion.

Anyways take a look at the following video to learn more about the upcoming Guild leveling system and Guild talent tree:

This is yet another HUGE change coming to the Cataclysm expansion with a lot of stats being changed or totally omitted from the game. The main change which will reflect every single class would be Stamina.

Also they are introducing a new melee Legendary weapon named Shadowmourne. Back to the good old Molten Core days I guess.

Here is the video taken at the recent Blizzcon to guide you through each aspect of the item and stats changes coming to the expansion.

The recently announced expansion Cataclysm will feature high-level raid dungeons. Here is a preview video consisting of the following dungeons:

Abyssal Maw
Halls of Origination
Blackrock Caverns
Icecrown Citadel
Icecrown Dungeons

Well the much rumored World of Warcraft expansion aptly names Cataclysm has finally been announced by Blizzard at the recent Blizzcon. Personally, I feel it would be a mouth watering expansion although not much new elements has been added to it. Perhaps the secondary profession called Archaeology and being able to fly in Azeroth is the most interesting aspect for me.

Anyhow without further ado, here is the awesome official video for those of you who missed it:
