How to gear up a druid at level 80 without ever entering an instance

One of the things that many guides for gearing up a druid assume is that you are willing to run heroics to get gear. Nothing against 5-mans, but I'm not ready to depend on a chance drop for gearing up. That's why I give you this guide. It gives you ways to gear up your druid without ever needing to run an instance. In other words, you can do do it all alone (with the exception of crafted items). I'll also give you multiple options for a specific slot when your best choice is either expensive or takes a long time to get.

Disclaimer: Some of these items are difficult to get if you don't enter an instance, as it will be more difficult for you to get the associated reputation. It is possible, though, to get exalted with the associated factions without running an instance, and that's the point. If you need help on getting exalted with those hard-to-level factions, check out my guide on said topic here.
