The recent Cataclysm Patch removed all portals from Dalaran except for Caverns of Time and PvP Battleground/Arena; and all portals from Shattrath except Isle of Quel’danas. Instead, you will find class trainers where the portals used to be. This is a painful tradeoff in exchange of flying in Azeroth, but one we will have to get used to. With the absence of a new major city hub like Shattrath was for Outland, and Dalaran was for Northrend, players must get back to their roots: Orgrimmar and Stormwind as the main hubs for Cataclysm.
Both major cities have portals to the high-end content regions: Mount Hyjal, Vashj’ir, Twilight Highlands, Deepholm, and Uldum. On the other hand, players with low level characters will have handy class trainers in Outland and Northrend and won’t be populating Orgrimmar as much.
[BLUE]The reason the portals from Shattrath were not removed from Outland when Wrath of the Lich King released is that there was a new central hub with portals to all major cities in Northrend. There is no longer a neutral city hub which both factions will be using in Cataclysm. We want to ensure visiting the major faction capitals is still the most attractive thing to do in Cataclysm, rather than having people use Shattrath and Dalaran as easy connector hubs.
To make up for this, we’d like to add class trainers and Auctioneers in Shattrath and Dalaran for those leveling through The Burning Crusade and Wrath of the Lich King content.[/BLUE]
