With "Ready for the Fight", you can make different setups for every Pandaria raid bosses. The addon will check your talents/glyphs and warn you if needed. Before the boss, a movable icon with a mouseover tooltip will appear and tells you what to do so you can change everything before the pull. You can turn in buff/stance/item checks too, therefore you won’t forget to unequip your Kirin Tor Signet and items like that. If you have to change your defensive CDs, utilities and healing abilities frequently for the maximum performance, then it’s the addon you need.
Currently the addon only supports Pandaria fights without the outdoor bosses.
