WoW Druid Simulator for Excel

Ok, I'll admit that I have no real idea what this thing does, or if it's even useful, but I figured I'd let you guys be the judge of that. FileFront.com is hosting a user-created Druid Simulator for MS Excel that allows that allows "druids to test their gear setups. It should allow them to determine which gear to aim for."

So, I guess it's a spreadsheet kind of thing? Personally, I don't get into the minutae of stats & all the numbers when I'm playing an MMO...or any game, for that matter...but I know there are plenty of folks that do, so maybe some of you will find this useful. You can download it from this link.
