He means after that Mutilation idol the other ones are BiS for you.
So Mutilation is BiS.

If you read the tooltip for The Idol of Mutilation it says the 200 agility has a chance to proc on Mangle and Shred. It seems to have nearly 100% uptime too.

Corruptor only gives 153 agility, so whether you have to mangle or not Idol of Mulitation is BiS for all dps feral druids.

Well, as I said with simple basics calculs you can easely prove that Shred always do much dmg per energy than rake, and the 2% proc dont make it good even. So why does FBN wants you to keep rake up ? There is a mistake somewhere. You can look my stats and stuff, armory link works.

@Haargot:

FBN doesn't want you to keep always rake up. FBN want you to use rake if rake is better. Actually shred should be around 10% more DPE thank rake to be better due to higher CP generation given by the lower energy cost of rake.
The FBN addon takes care of 2T8 bonus, 2T9 bonus and everything else. There are situations where shred became better than rake but are situations. Actually it also depends on your ap and crit because those abilities scales differently with them.
With a standard T8 itemization you'll reach a situation where shred is better than rake only with procs (for istance mongoose/berserking + grim toll or the rune), with T9 gear level expecially if you are going for the passive arpen cap you will reach the shred>rake scenario but 2T9 will save it. With 2T9 bonus (3 more seconds on rake), rake will be better (in general) than shred again and probably Blizz has introduced that tier bonus for that reason.

The damage bonus you gain from Tigers Fury is cancelled when you use Berserk. Thus, you should allow the Tiger's Fury buff to wear off before using Berserk. Remember the instant energy gain from using TF is something you spec into.

Thank you for compiling all these information and coming up with this thread. My question is about the BiS list, the feet slot specifically. I won Treads of the Icewalker the other day and equipping it made my ArP at around 223 although I'm gemmed for agi. Isn't this item better than the crafted boots? Another question, shall I regem for ArP now that I've reached this bit? Thanks in advance.

Another reason besides the damage buff, is if you go into berserk presumably with rip and SR still up, you can easily get off 2 FBs, then refresh those(rip and sr), then right after berserk get in another FB with TF

I recently got away from using TF and Berserk back to back, took some mental retraining.

I was always under the impression that you keep Rake up but don't clip it to refresh it, as you lose a DoT tick that way.

Am I incorrect in my memory that at one point the priority was keep up SR, Mangle, Rake, Rip, you could cliip SR but shouldn't clip Rake, Rip or Mangle? Shred was your CP generator in the interim. Should I be using Rake to generate CP if the DPE compare is better and not worry about the dot ticks?

I'll fiddle with some DPE readings for my particular gearset, but I'm interested in what the boundary/threshold values are that tend to drive that comparison to go one way or the other.

Would be ironic if all this time I've been doing it wrong.

There was a arguement that went on for a few pages in one of the threads about feral DPS that discussed this, but I could never find a reliable answer on it as no one seemed to find a definite, just a bunch of "what if"s and "should"s.

If this is correct, then when do you pop berserk? Do you just pool energy and stop attacking until about 70-80? I've always done it TF - Berserk for full energy.

Keep in mind the TF bonus only lasts 6 seconds and has a 30 second cooldown, with Berserk lasting 15 seconds this gives you a 9 second window in which to pool energy for the Berserk, this is essentially perfect because Berserk is on the GCD so you'll get to 100 energy before you can use another ability, though with lag and the unlikelyhood that you'll be at 0 before this 9 second period, you're better off Berserking at 7 or 8 seconds after TF wears off (17-16 seconds left on the TF Cooldown is a handy point). Ideally, you should refresh Mangle and Rake during the TF Bonus, but don't clip Rake in order to do so, likely you can delay the activation of TF (or Berserk, which will also delay TF) but that may be worse than simply having Rake downtime.

Jheusse: The DPE from Rake will never be better than Shred without the DoT tics, I don't know how you think that's even possible at your gear level (not just mechanically, but experience wise you should know better!) When people are talking about "should we be using Rake" right now, we mean "should we be using Rake at all" since with high Armor Penetration, Shred easily passes Rake in terms of raw DPE.

In terms of priority: SR, Mangle, Rake, Rip. It's not just ok to clip SR, but also Mangle, and I recommend clipping them infact to prevent unnecessary downtime due to lag/misses. Never clip Rake, really no point in clipping it anyway. Rip can be clipped in various circumstances like at <6 seconds left with 5cp and nearly full energy, or (and I recommend doing this) when about to switch off of a Boss for a while (Razorscale taking off, Sapphiron frost breath, Heigan dance phase, Yogg Brain, etc.)

Thank you Murna for this valuable thread. Using the info from your post, I am able to get my kitty dps up to 2.7k on 5 man heroic trial on my first day as a kitty.

My question is, what is the stat priority for haste and crit? Which is more important and why? What is their importance in relation to the other major kitty stats?

Thank you.
