Feral Help Please

Hi I play a feral druid and always have. My dps isn't too bad, however there are some bosses where my dps is just low and I'm not understanding why this is. For example I can do about 35k on heroic morchok but then do like 29k on Hagara, but when it comes to heroic Ultraxion I'm usually always the last or second to last person on the dps meters above the tank where I can't seem to get past 34k.. I just don't understand why or what I'm doing wrong. @Notdiggz could you possibly figure out what I'm doing wrong or shoot me in the direction of a feral dps forum? Here is my armor link: http://us.battle.net/wow/en/character/m ... i/advanced I'm not even sure if I'm reforging right for this gear that I'm in. Everywhere and everything I read says that all the secondary stats are equal for DS and that it doesn't matter which you go for.
