Feral Druid Dps Problem.

Hello everyone I am new to this section of Neoseeker and found this to be the most logical place to post this and get answers.

I'm a lv80 Night Elf Druid (Feral/Resto) (Yes ally, don't hate).

Now my problem is that with the gear I have ( My Gear ) I feel I should be pulling more dps then I am doing which is anywhere from 2.4k to 3.4k in 5man heroics. But mainly is below 3k (on bosses I pull 4k-5k dps 85% of the time), I'm not quite sure if its my rotation or maybe I am doing the proper amount of dps for my gear.

My rotation is the following.

1. Mangle, 1-2 combo points.
2. Savage Roar
3. Rake
4. Shred till I have 5 combo points.
5. Rip

I'll rinse and repeat. If my rip and SR have more then 8 seconds on them and I have 5 points I'll occasionally FB.

So I'm wondering is something wrong with my rotation?

It also could be the tanks for all I know, if they move to much I have to constantly reposition myself behind the mob which doesn't seem that big but it actually does deal a blow to my DPS.

Any input and information would be greatly appreciated.

P.S If anyone is wondering why I have improper shoulder and head enchants its because I'm extremely lazy when it comes to farming rep.
