To be fair, it's incredibly easy to get bored with current content. Sure, things like the Molten Front and Firelands are fun and exciting for a while, but several months later when you find yourself running the same content over and over ... well.
I'm always looking for new and different things to do with my shadow priest. Last year, when I started getting bored with Icecrown Citadel, I started running heroic Magisters' Terrace solo, farming it for all sorts of goodies inside that I never wound up getting when the content was relevant. It turns out that soloing that stuff was a lot of fun, and judging by the emails I got after, a lot of you agreed with me.
Some of you have been pressuring me to update that article for Cataclysm. Obviously, a lot has changed. Mainly, we've gotten stronger, but we've also got a few new tools at our disposal. Soloing Magisters' Terrace is old news. This time around, we're going to solo some more intimidating content: Wrath heroics and BC raids.
