### Introduction

It’s been a while since I’ve done a legitimate theorycrafting post. We’ve had everything in MoP figured out for so long that there hasn’t been much incentive to do anything further. However now that we’ve started getting information about Warlords, there’s new things we can do! But first, a story.

A while ago I wrote a little story about how I got into theorycrafting. Normally this wouldn’t be pertinent, but part of this story was about making sure things are accurate and how to do that. One of those ways is of course, to ask for someone to look at your work. Kind-of like proof-reading.

Something that you may also not know (well some of you will) is that while I’m pretty decent at algebra, I’m really terrible at calculus. So I’ve had people review my stuff before, and did so again today. Thankfully both Theck and Ahanss made sure I wasn’t totally off my rocker. Theck may have also implicitly questioned my intelligence (he’s my friend, he’s allowed). I kid, I kid.

In any case, I’m here to talk to you today about Guardian Rage generation in Warlords of Draenor. At least, what we know about it from the alpha patch notes. Well, the first half of it anyway.

### Spreadsheets and Simulations

In the current iteration of Guardian development, there are two different distinct possible rotations: With and without Pulverize. Today’s post is going to focus on the latter, more simple version of this rotation. Now, before we get into anything specific it’s important to understand that the most *accurate* way to investigate this kind of thing is through simulations which replicate gameplay. However it’s very possible – and usually much easier – to get *most* of the way there using a simple spreadsheet. Enough in any case, to pick up on any potential problems that might occur as gear improves throughout an expansion.

You may have seen me mention on Twitter that I want to get into working on SimC. I originally thought I would simply re-teach myself Java and build my own simulator, but Theck convinced me otherwise. Until I manage to teach myself C++ (or whatever they use) to a degree that I’m able to do anything productive, I will approximate situations using spreadsheets as best I can. That’s what I’ve done here. In order to do that though, I made a few assumptions.

### Assumptions of Play

The results I will describe shortly are based on a set of assumptions of how a Guardian would play while tanking a boss. These are:

- 100% Thrash uptime.
- 100% Savage Defense uptime.
- Mangle is used on CD.
- Empty GCDs are filled with Lacerate.
- Tooth and Claw generates Rage when it crits.

Fortunately I can prove all of these assumptions – with a reasonable degree of accuracy – using math. First, we know that Thrash‘s duration is 16 seconds. We also know that the chance of not getting a Mangle proc on 2 consecutive Lacerates is 75%*75% = 56.25%. Bare nekkid our GCD is 1.42857 seconds (5% Haste raid buff). That gives us 16 / 1.42857 = 11.2 GCDs every 16 seconds, or almost 12. That means the chance of not being able to use a Thrash on the 3rd GCD after a Mangle is only around 3% ((1-0.5625)^4).

Second, we know that the RPS to maintain 100% SD uptime (for 42 seconds) is only 6.6666~ if you bank 100 Rage before swapping. Since Mangle and Lacerate together generate at least 10 RPS without considering Mangle procs (60/6) or Haste, then that is definitely possible. I also assume around 10% base Dodge from Agility, which is about what we had at the start of the expansion after suppression.

My third assumption is pretty obvious, since Mangle does the most damage and generates the most Rage. As is by extension, the fourth. The actual formula for calculating the number of Mangles is something I re-purposed from Helistar by removing the “miss” and changing it to a variable GCD based on Haste. We know this formula is accurate to at least 3 sig-figs because of Tangedyn’s simulations during MoP Beta.

The fifth and final assumption is implied from the wording of Primal Fury although never confirmed.

### Results

The “TLDR” version of the results is that we’re going to be swimming in Rage, and Crit is worse than Haste in the current build until you reach GCD cap. The longer version has a bit of exposition along with visual aids. For example, this is what the graph looks like when you are completely naked and only have raid buffs.

We start at just over 18 RPS with this rotation. To provide a relative example, this is approximately the same amount of RPS we have now in heroic SoO gear. The obvious difference between the two examples is that Tooth and Claw is now *free*. This liberates an absolutely **huge** amount of our Rage for Frenzied Regeneration. But what happens when we add around 500 Crit and 500 Haste, an amount you might attain in Warlords dungeon gear?

Haste is still better, and our base generation has grown to 19.5 RPS. What about 1000 Crit and 1000 Haste, something you might see in the first raid tier?

We’re nearly hitting 21 RPS, and Haste is still clearly the superior stat. But what if we choose to purely stack Haste, since it’s clearly objectively better than Crit?

Over 21.5 RPS, and Haste still generates more Rage than Crit until the GCD cap.

### Conclusions

There are two very clear conclusions visible.

- Crit is objectively worse than Haste until GCD cap. Even if the two generated similar amounts of Rage, Haste would still win because of the mitigation benefit from Tooth and Claw, and the increased uptime of Ursa Major.
- We are potentially generating
*too much*Rage simply by executing our rotation.

In order to fix (1) Crit needs to either generate substantially more Rage than Haste, or also contribute to our survival in some other manner. However even if you simply increase Crit’s contribute to the Rage pool, I’m not convinced that the additional benefits of Haste won’t continue to outweigh it. Especially given how much base Rage generation we have.

(2) is something that is impossible to evaluate without knowing what Blizzard’s targets are. The concept makes sense from a high level though. The higher our base Rage generation is, the more incentive we will have to seek out secondary stats that do not contribute to Rage generation. I’m just really worried that our base generation will be too high, especially after Tooth and Claw becomes free.
