Ok I've uploaded the spreadsheet to a SaveFile project so that I don't have to keep changing the damn links.
Spreadsheet can be found at this project- http://savefile.com/projects/1018107
This spreadsheet allows you to quickly compare your stats for a given selection of armor based purely on the merits of the stats alone. While this started out as just a way for people to compare Tier 3 to Tier 2 to look for the best upgrade value, its grown into a bit more.
v3.2 of the Armor Analysis
All errors posted in the previous thread have been corrected.
Mages are now back in the spreadsheet. (Sorry!)
Rogues stats are fixed.
Hunter T3 stat fixed.
Added about 8 items to the shaman tab.
If you would like other items added (additional tanking items, etc) post a link to allakhazam or something similar in this thread and I'll start adding them in.
