Just read it at curse - WHAT THE HELL?
Path of the Titans, a really cool idea - gone.
Guild Talents - gone. Now every guild will be the same, no way to "specialize".
Guild currency - gone.
But now we can grind reputation with our own guild.... uhm.... wtf? Do we really need yet another faction grind? I really hope you get reputation for basically doing anything while in the guild, levelling, raiding, dungeons etc.
Uhm.... Deathwing enters through the Maelstrom now? what the ... Ok, if they do it well I might buy it, still... doing a retcon, sort of, already?! Seriously, make up your minds before announcing one thing to the world and then doing another thing.
Now that DW enters through the Maelstrom we better be able to go there to seal it or something. Being able to go to, to see the Maelstrom would be a major, major bonus for me and would make me overlook the Path of the Titans thing etc.
What I like:
The emphasis on "acting" warchief. ^^ The story leak at Spooncraft already convinced me that there's a good chance that Garrosh won't stay Warchief, or if he really changes might stay Warchief (a better person then though) or after Cataclysm go back to being Thrall's number one, having earned the right to be his heir (which doesn't seem to be true right now, what we've seen of what he does in Cataclysm).
Really like the "joining other IDs" thing. We're doing a 10man in our guild and couple other guys from the 25man also a 10man. Often, on the second day of raiding where everyone already has an ID, either they or we have not enough players to continue while the other raid often has a surplus of players. This way we could simply switch players to fill up both. Very nice.
New music - major bonus imo. I really, really liked the Wotlk music, much, much more than the Vanilla or BC stuff. If they add Wotlk-quality music to the new Vanilla content - hell yeah!
