Rumor has it they nerfed the amount of gold that Onyxia drops as well. At least from the 3-4 people I heard from last night. I am probably going to pop her tonight and see what I get.

I usually get anywhere from 140-180g from killing her and the reports I was hearing last night was it was down to 50-60g. Sadly enough, that still isn't a bad amount of money, but it's confusing because they are really toploading the economy with the changes they are making. You won't start making serious money until you are 80. (I really don't believe that at all, but it just seems that by some of these changes, they really are driving it that way.)
