I use NeedToKnow to setup nice bars for SR, Mangle, Rip and Rake.

I also use PowerAuras to track missing Faerie Fire and Mangle/Trauma.

Sorry, but... no.
It has been stated several times in these forums, that tun makes some remarkable mistakes and his guide has some severe errors as well.
I am sure, there a lots of druids here that will provide better DPS values, if they have access to the same gear and buffs (tun got hysteria chained in nearly every fight)

Concerning the macro: Yes it would be better to make some moves after using TF and then let the energy pool to 90.
But you should make sure that you don't lose uptime of something.
And this is a beginner's guide. I thought cat priority cycle is complex enough, that's why I simplified the use of TF and berserk.

Regarding feral addons: I personaly prefer Droodfocus to any other buff/debuff tracker (including badkitty).

I use Droodfocus along with FBN.

I was using Droodfocus, but I found that in Ulduar the CP display became a solid, white block. I am unsure if this only occurs for me, but it happened every time I entered Ulduar. I switched to FBN, which I found to be very customizable for my needs.

This is incorrect. Hit is good, but agility/armor pen are better.

It's not incorrect that hit cap is good. Hit is especially important for applying Rip and Rake, and it seems like most cat theorycrafters ignore or don't realize this.

Armor pen and agility are fantastic and I did not say they are better or worse than hit. I said nothing of excluding any of them.

I just shared what I do and how much dps I do with that and why.

Logic, ftw.

Weighing raw stats against each other is only a level playing field when intangibles like a missed Rip or dodged Rake are accounted for.

Hit rating is useful for avoiding missed white attacks and specials like Shred, yes. But it's huge for applying the crucial debuffs of Mangle, Rip, and Rake. Every time you miss one of those specials, you've just wasted a GCD to reapply that should've been a Shred.

In that situation, how is 20 armor pen rating better than the 20 hit rating you'd need to avoid the missed debuff completely?

This is incorrect. You don't tend to waste a GCD unless you're in unlimited energy mode, which is typically only in berserk. So hit is better if you're berserked, but that's 15 seconds out of every 180 seconds total.

The rest of the time, you don't waste a GCD most of the time as you're operating at or close to an energy deficit. In other words, you're waiting on doing that attack anyway, so all it means is that you aren't applying the rip or rake as fast as you could. That's not optimal, but it's not 'missing a shred'. It's delaying a shred, at worst.

Because for the rest of the fight that you didn't miss the debuff, that 20 armor pen was helping you more then the 20 hit.

Kitties are not GCD locked in our dps cycle. CP gen and energy are what limit and determine what kind of cycle we strive for. That 20 armor pen would apply to all of your non bleed attacks for the whole fight, while that 20 hit to not miss ( I'll assume like you did even that the 20hit is all you need to cap hit for the sake of this argument ) has maybe lost you over the course of the fight 1-3 OOC procs ( I am being ridiculously generous here, missing even 1 is rare that close to cap ) and maybe a grand total of 2-3 seconds of debuff down time.

Primal precision and energy refunded from a special attack make it so that a miss / dodge / parry is for most intents and purposes simply a gcd loss to reuse the last attack that missed, and if it was a finisher its 20% energy lost from the cost of the finisher which just for example is only 6 energy for Rip.

Now does this mean I think hit is useless, definitely not, but the goal is to never gem or enchant for it, and to simply use pieces that are good due to armpen / agi that also have hit and expertise. This way you get close to the caps while still gearing for the desired stats.

I think the argument about gemming/enchanting for hit vs. ArP is moot because so much cat gear comes with enough hit to put you over or near the cap.

The more interesting discussion for cats is really gemming/enchanting for ArP vs. Agility.

I like this statement in this thread regarding that:
"As far as the current theory is concerned, once you reach the trinket soft cap on ArP (556), you want to start gemming agility (while maintaining the soft cap, of course). It's certainly possible to do well by simply gemming agility because you end up with a broader and consequently higher range of potential DPS than if you had gemmed ArP (Nightcrowlers work is a worthwhile read, the section about DPS dispersion is about halfway down his OP). Also, there is a school of thought that values gemming agility on fights were burst DPS is important (like yogg)."

This is all very true, but this forum is about min-maxing to get every ounce of possible DPS. Hit is not the stat that will deliver the most bang for the buck, and thus why it is devalued from a max DPS perspective. Now, this would be very different if more fights included mechanics like Emalon, XT, etc. but the reality is they are in the minority.

The secondary argument to these kinds of fights are that we build secondary and tertiary sets just for this very reason. Yogg definitely requires more burst than sustained DPS, at least until phase 3 (depending on how one's guild handles phase 3) which would value hit and agility far more than ArP. In this case a secondary set becomes more optimal than gearing for hit in just one cat set.

The point has been made that hit and expertise are not bad stats by any stretch of the word. However, mathematics and in game testing have proven that they should never actively be sought after. As Nytkin mentioned, they will often come by default when grabbing Agility/ArP gear.
