I’m not doing a heck of a lot of preparation for Wrath of the Lich King.  That being said, I am doing two things to prepare. 

prepare I’m buying cheap herbs so that my warlock can level inscription as quickly as possible.  Right now he’s one of my three miners, so it won’t be hard to drop mining for inscription.  It looks as though there will be a lot of neat abilities opened up with inscription, so I want to level that as quickly as possible. 

The other thing I’m doing is leveling alts.  I have a druid, shaman, and warlock around level 50.  I’d like to get them all to max level before the expansion – that’ll give me 6 toons to level to 80 (7 if I decide to level Flint).  If Wrath takes too long to come out, I’ll probably level another priest.  I’m hoping that Wrath will allow some kind of insta-leveling so that I can run a priest with Jaimie’s death knight.

One big thing that I’m not doing is stocking up on gold.  With 3 level 70s, I could theoretically be pulling in 600ish gold per day by doing daily quests.  I just don’t want to do dailies – at this point the only reward for doing them is gold.  If there were a way of doing 5-10 dailies for a badge of justice, I would do them, but as it stands it’s just not worth it.  I have  epic flying mounts on all three of my max-level characters, so what am I going to do with more gold?  I’m playing the auction house conservatively which takes me about 15 concentration-free minutes a day and makes me a decent trickle of gold.  For now, that’s enough.
