Warrior: Class Portal
The purpose of this page is to serve as a collection of links to useful resources that are fully dedicated to getting the most out of your Meat Shield.
Max DPS - Great tool for organizing and sorting what gear you might want to work towards.
Tank Spot - This is considered THE resource for warriors and tanks in particular, Tank Spot has detailed guides, discussions, and videos for tanks, DPSers, and Arena players. Covers builds, gems, glyphs, food, everything for both PvE and PvP.
WoW Loot Tables for Warriors - Make sure you know what boss drops what loot before you show up.
Elitist Jerks - Warrior Discussions - Elitist Jerks is web forum for theory crafting and general thought/debate about classes. This link will take you to the entry point, pick the thread you need from there. Unlike the Blizzard Official forums, they don't allow just anyone to post so the 'noise' is kept to a minimum. This is the place to go for a 'deep dive' discussion of class mechanics.
Arena Junkies - If you like PvP at all, spend some time checking this site out. Great resource.
