I have six as well, but can blame it on being unemployed for a few months. No income and pretty well unlimited free time are a recipe for spending a lot of time on WoW as it effectively costs almost nothing. I spent a lot of time screwing around on the AH as well, with a goal of getting to the gold cap on one character, but didn't quite make it (got to ~200k). Thankfully I doubt I'll get anywhere near that many 85s as I an once again among the ranks of the gainfully employed.
