Umm... We are trying to help. Sloniah scolded JeeBar for being slightly mean as that is not the way of the druid fourms. You are being confrontational for no reason, which for a new comer is not a good idea.
Your attitude sucks, much like your spec. You seemed unsure why people said as much. Well I will tell you.
Lets start with what you should have at level 66. I am assuming judging from your gear that you mainly solo play as the armory tells when gear is from instances and you only have one such piece. This matters for DPS as solo and instance DPS differ in how they work.
Level 66 DPS spec for a mainly solo play feral. Ferocity(5/5): Makes your primary attack, Mangle, cheaper. This will enable faster combo point generation. Which leads to faster kills.
Furor (4/5): Enables you to have energy as soon as you switch into cat form. Only 4/5 due to the new energy mechanic. The other point goes into Imp Mark to make you buff stronger. More so because the 5th point is less effective than the other 4 and it can be spent else where to better effect.
Naturalist (5/5): Gives you 10% more damage. That is a huge increase for the amount of points spent. You take it and go for it as soon as you get Mangle.
Omen of Clarity : This talent is a far greater increase in DPS than Berserk for a DPS build. If you don't believe me go to elitistjerks.com they do math. They are not as nice as us but if you doubt me try find the reference or post there and ask.
The wasted points. These are points that just don't help DPS that much at all compared to points spent elsewhere.
Imp Mangle: The points can have a greater impact on personal DPS elsewhere. The effect is far stronger for bears. The energy cost reduction is weak considering how deep in the tree it is.
Feral Aggression, SotF, RnT, Berserk. Its isn't so much any one of these just that the combo of all of them doesn't let you take the DPS gold in the resto tree. Plus many of them are more instance DPS or bear oriented. As they relate to Maul and Shred rotations.
The spec I listed gives you the increases from 3 points in Feral Aggression; as I assuming you love dumping big energy into Ferocious Bite. Which is a DPS loser unless it kills the mobs outright and there are no more mobs to kill before all that energy regenerates. Which is why the points in Rend and Tear are not very well spent. Especially if you are not using Shred all time in an instance DPS rotation.
Seriously, your spec is seeming like it wants to be a level 80 DPS spec but is missing points and a definite rotation plan. You are guessing and trying to figure things out. That is good. But mechanics are immutable. Ferocious Bite is a DPS loser when done with over 35 energy if I recall in any serious rotation and feral DPS rotations will be complex at a high level with the addition of Savage Roar at level 75.
Ferocious Bite has good burst. That combined with the resilience nerf is why you are winning duels. Duels are not a good measure of DPS. If you are trying to PvP then again your spec is weird. You want Primal Tenacity and Natural Shapeshifter for a serious PvP build. A PvP build would be more based on keeping up bleeds and burst with good survivability. This is what I would do for a
level 70 generic PvP build . PvP is not my game so I could be off on that one.
Yes, druids tank as bear form. They also have different specs than cat druids. With some differences in gear selection as well. Ferocity as previously stated is for all feral specs. Primal Tenacity is a PvP oriented talent, more so now that the tree is bigger with less extra points to spend on electives. Other points where made in other parts of this post.
But hey that's just my opinion.
