Here is a look at what I've done so far. It is completely rewritten and has only current Cataclysm changes in it. I plan on keeping it up to date with any future class updates, including putting in ways to include your gear profiles and other enhancements.
The spreadsheet only currently works with Excel 2007.
It has no support for items currently because it is being designed for level 85, not the current content. However, it works for level 80 as well, and I plan to keep it current with any changes. I plan to make it much more accurate, with support for armory and item upgrades.
