Before the beginning of Cataclysm, I knew there would be a lot of moving around across the globe. I didn't realize portals would be in Stormwind (or the Horde's Orgrimmar) such that people would just move in there. Because I was dumb, and not a mage, I started acquiring a few items. I've added a few but they all seem to come in handy for various activities. Here's my list.
[Direbrew's Remote] - Need a quick pitstop? Need to smelt some dark iron? Want an ugly hearth between Ironforge and Stormwind? It's better than a boat or zeppelin. Just don't be a jerk and use it a BG and ask people to click it for a present.
[Baradin's Wardens Tabard] - This is a wonderful secondary hearth. Land in the quest hub and click on the portal to Stormwind. Or you could actually do your dailies if you're going for a mount or pet.
[Wrap of Unity] - Another wonderful secondary hearth that level 15 Cataclysm guilds can provide. There are Horde and greater / lesser versions.
[Band of the Kirin Tor] - How often do you need to get to Northrend? Or Dalaran? No? What about going to Dalaran and taking the portal to the Keepers of Time and Dragon Soul instance? This thing used to be considered expensive. Now a few thousand gold is pocket change. There are other styles and upgrades, but there's really no point to them other than the hearth.
[Blessed Medallion of Karabor] - Need to get to Outlands and not near a portal to The Portal? This will get you there nicely. And if you're doing dailies for your drake mounts you'll crave this item.
[Argent Crusader's Tabard] - Would you like another Northrend port? How about to that dailies hub that has all those mounts and pets? For DPS waiting in a queue, this is a nice immediate activity.
[Hearthstone] - The list wouldn't be complete without this handy item, right? Level eight guilds augment it with[Hasty Hearth]. A long time ago, I accidentally dropped mine. I was quite relieved to learn I just needed to talk with an innkeeper for a new one.
[Stormpike Insignia Rank 6] - If you're a BG'er, this can have its uses; This is especially true if you're going for achievements.
And there's simply hoofing it. But hunters should do it in style: [Master Riding], [Mount Up] and a [Blue Dragonhawk] (ss).
If I was an engineer, I'd have a generator or two, but alas I'm stuck in my ways and not going engineering. I'm also not interested in expensive consumable hearths to Deepholm since I'm not an alchemist.
And if you're in a group, you should show that you're extremely fast and a gentleman to the lesser classes by tossing a [Have Group, Will Travel] summon.
