EOTM is nice in that you can just afk it and farm karma/xp (Provided you are winning atm).
Other than that, crafting did get nerfed significantly (8 vs 10 levels), but you can get an easy chunk of levels from cooking (If you have an 80 to get you karma items its even cheaper, like a few dozen silver last I checked).
http://gw2crafts.net/ has various guides for crafting, JC is also very cheap compared to cooking.
