I love my death knight. He will probably be my main for as long as I play WoW. That said, sometimes you want a change of pace. Sometimes, you've finished all the dailies, ground all the factions to exalted, and run every heroic dungeon and raid on a single character until your eyes are bleeding. Sometimes you want something else. And for that, we have alts.
Of course, alts don't mean you've completely abandoned your death knight. Sometimes, alts teach you something about your death knight. In my case, most of my alts were created before the death knight, since he didn't come along until Wrath. That means that a lot of what I learned playing them has informed how I play my death knight from day one. This week, I'm taking a look at my stable of alts and seeing what lessons they've taught or reinforced for me about my death knights.
Keep your diseases up
I've been playing a warlock alt since the vanilla era, sticking mostly to affliction, although demonology's been proving pretty fun so far in Mists. My priest I don't play quite as much, but I still like taking shadow out for a spin every once in a while.
