Spiritual Guidance: Paying the hybrid tax
Every Wednesday, Fox Van Allen uses his dark, shadowy powers to take the reins of Spiritual Guidance, causing severe harm to others in the form of large, yellow five-digit numbers. Holy and disc brethren, alike — come join the dark side before his shadowfiend eats you.
Fact: Priests are pretty much awesome.
It's because we're versatile. We can DPS the living snot out of Lord Marrowgar in shadow, and then change to discipline so we can cover the raid in Power Word: Shields and Renews for Deathbringer Saurfang. Heck, we can even do both. We're just that awesome.
But awesomeness comes at a price, my friends, and that price is called the hybrid tax. It's the term commonly used to explain why our DPS is designed to lag behind that of mages, warlocks, hunters, and rogues — the pure DPS classes. If you're a jack of all trades, you're supposed to be a master of none.
(It's cool though, they need the handout. It really sucks not being a Priest.)
We can be forgiven, though, for looking at Recount or a World of Logs parse and thinking that whatever the hybrid tax is, it's just way too high. But is it really? Are we finally doing the kind of damage that we should?
The long road to 3.3
It can be very frustrating playing as a DPS class. There is, and will always be, a natural tendency to measure our self worth by one number and one number alone. And it's just never going to sit right that shadow priests (along with our fellow hybrids such as moonkins and elemental shamans) have a built in, permanent disadvantage in the DPS race.
One of the major issues shadow priests have faced during the Wrath of the Lich King expansion is the hybrid tax — specifically, the tax being way too large. Scaling in Naxx and Ulduar was terrible, and Blizzard justified it by the tax: "Priests can heal, so who cares if they stink at dealing damage?"
It turns out that raid leaders cared. A lot of decent shadow priests lost raid slots; countless others were told to switch out to healing if they wanted to keep their slots.
If that wasn't an indication of a problem, I don't know what was. Thankfully, shadow priests got a treasure trove of buffs last month and have had ample time to put these buffs into use in Icecrown.
There's a heck of a lot of heresy and ancedotal evidence about where shadow priests — and other classes — are DPS-wise right now. Visit any forum, and you'll find people complaining. You really can't look at any one player, or any one raid, though. Gear levels will never be equal, nor will skill. To get an accurate picture, you need to look at some hard data. The right data.
Calculating the hybrid tax
Before we can figure out whether or not shadow priests are performing up to par, we have to figure out what par is. Let's try to set a few basic ground rules so we can get as fair a comparison as possible.
First, let's define the data and where it comes from. WoW Meters Online provides some pretty handy data here — for each fight in Icecrown Citadel, WoW Meters provides an average DPS for the top 50 performers per class per fight. This helps us normalize skill by choosing (presumably) players of a similar, high rate of skill. (Or maybe luck.)
Second, we'll only measure shadow priest DPS against other ranged classes — hunters, mages, and warlocks. This effectively takes rogues out of the equation (something I wouldn't mind doing every time I PvP). The logic: Some fights will favor single-target melee over ranged — Festergut, for instance — but few fights will significantly favor one flavor of ranged over another.
We have eight separate 25-man ICC boss fights available to look at, from Lord Marrowgar through Blood-Queen Lana'thel. (No fair looking at the Gunship battle, you AoE-ing little cheaters.) The data, taken January 26, is in the following table:
