There have been a lot of requests for this funny image. It is a parody flow chart of the Feral Rotation from Wrath of the Lich King. So a bit of history.
During WOTLK Ferals had all the same spells as they have now, the difference was the durations. For example; Mangle only had a 15 sec duration, Rake had a 9 sec duration & Rip was 15 sec but could be extended with the old Glyph of Shred (Every time you use Shred, it extended the duration of Rip by 2 sec up to a maximum of 6 sec). Also due to the way our damage was structured, you dps really plummeted if you let Savage Roar drop off. The short durations of all the spells in combination with managing Savage Roar made the “rotation” very complex and hectic when combined with encounter mechanics, raid awareness and utility. I discuss Feral Druid utility in last weeks post.
Thankfully we have had a lot of quality of life changes to make things easier. Rake has had their base duration increased to 15 secs. The old Glyph of Shred is now a passive part of the Rip spell. The old Blood in the Water Cataclysm talent baked into Ferocious Bite to give Ferals a passive, permanent execute, rather than just weaving in the odd Ferocious Bite as it was during WOTLK. In Cataclysm the Mangle debuff duration was increased to 1 min and now in Mists of Pandaria it has been removed entirely. There is now a glyph available that allows you to cast Savage Roar with a 12 sec duration with zero combo points. So without further delay, here it is in all of its glory.
If you have any questions about the changes to Feral Druids between Cataclysm and Mists of Pandaria there is a good guide / summary over at WoW Head or you can contact me directly by leaving a comment on the post, sending me an email at firstname.lastname@example.org, sending me a tweet @Elamari_ or leaving a comment on the File Under Feral Facebook page http://www.facebook.com/FileUnderFeral.
