I do have one problem with Cataclysm, which is neatly summed up by NPC Comic
The shaman is currently in the 60’s with heirlooms on, simply so I can nuke through the Outland content as fast as I can. To delay the moment of entering the old content he worked through all the possible quests in the Blasted Lands (though this was also to see the new content properly at level, hurrah for Worgen goodness).
Anyway, once I get back onto the levelling grind at the lower levels he’s on the priority list to get through and out of Northrend as quickly as possible.
