You risk not maximizing your AH value by doing this, but I quick sell any non-valuable duplicates. If you go through, position-by-position, you an clear our dozens or possibly even hundreds of duplicate players. Obviously those players may end up being worth a ton on the AH, but it's easier than jumping back and forth from farm teams and whatnot.
With that said, it appears farm teams may be the way to go. Of course, that's only AFTER I sold the 300+ bronzes in my collections on Thursday.....before the MVP's released on Friday.....FML.
