With Cataclysm around the corner, we have the opportunities for rare Feats of Strength; namely, Realm Firsts. Since I don't raid, I'm not going to worry about those. However, I would like to go for realm first on some professions.
Since I do have a lot of alts, doing the daily cooking quests in Orgrimmar or Stormwind nets me 1-2 Chef Awards per day, per alt, per server that I'm on. Now, on Demon Soul I'm going to try to have Bloodshrike get the Cooking and Fishing Achievements. Fishing I'm gonna try to get by fishing in the Dalaran Sewers, and hopefully I'll get the Rat while I'm doing that.
As for Cooking, with 9 other alts doing the cooking quests, and getting the crates of meat, that allows me to have access to a bunch of meat at the start of Cataclysm, which I'd probably not be able to get without leveling up to 81-83 first.
Now, I mentioned that I'm doing it on all my servers. Why? Two reasons. I've always been a sucker for Dailies, because I know where to go, and what to do. Especially when I have more than one alt doing them, I have my routine down to a science by the 4th toon. This allows for fast, easy XP and gold for all my toons.
The second reason is that if you're not going to use the meat, at the start of Cataclysm, I'm positive it will sell for ludicrous amounts of gold on the AH, to other people going for the Realm First, or just desperate to level up cooking for some reason. Since my highest toon on Daggerspine is 63, and on Darrowmere my highest is 52, I'll be selling the meat.
Save it until the day before Cataclysm drops, and post it late at night, so it's ready for people to buy buy buy!
