Icy-Veins Guides(Balance, Feral, Guardian, Restoration)
Icy-veins offers talent suggestions, stat weights, rotation guides, and more. As it is still early in the expansion, this guide may change as more data is available and new content is released.
Warcraft logs is a site where players can uplolad fight logs (amazing description, I know). It displays each fight according to different metrics and assigns a rank to players. Not only can you analyze fights that your character has done (provided it's been uploaded), you can also check out the top performers for different fights.
