Haste is a special stat for Fury warriors. It's promoted as the #1 stat by many guides, and it made me wonder why. I always saw Haste as either a technical stat, or as a secondary stat that only empowered others. So in an attempt to understand what's going on, I investigated a few of the feats of Haste.
- Haste increases attack speed. This improves your rage generated per second. I was sceptical about this benefit since it boosts attack speed similarly to cast speed. If you could auto-hit twice in a 3 GCD cycle before haste, you still auto-hit twice in 3 GCD cycles after haste. The GCD scales down with haste, so it's all going quicker, but it's proportionally the same.
- Haste reduces the GCD. Since most of our abilities are instant, this boosts the number of abilities we can use within a long time-frame, directly proportional to the amount of haste. For small time-frames, you get discrete intervals with the number of GCDs within that timeframe.
- Haste decreases cooldowns proportionally to the GCD. This is important to understanding rotations. A rotation of 3 abilities where one or two have a short cooldown (ie: Raging Blow, Bloodthirst, Furious Slash) does not change with Haste. The cooldowns scale along, keeping the rotation.
- Haste doesn't reduce the buff time. And this is the big benefit... A short buff, something we have plenty off, lasts as long regardless of haste. As a result, haste can help us increase the number of abilities cast during a buff timer.
Here's the list of caps for any number of hits within a buff frame.
|Avatar, 15 hits||5.0%|
|Bloodbath, 8 hits||5.0%|
|Enrage, 4 hits||12.5%|
|Avatar, 16 hits||12.5%|
|Battle Cry, 5 hits||20.0%|
|Avatar, 17 hits||20.0%|
|Bloodbath, 9 hits||20.0%|
|Dragon Roar, 6 hits||25.0%|
|Avatar, 18 hits||27.5%|
|Avatar, 19 hits||35.0%|
|Bloodbath, 10 hits||35.0%|
|Avatar, 20 hits||42.5%|
|Enrage, 5 hits||50.0%|
|Battle Cry, 6 hits||50.0%|
|Dragon Roar, 7 hits||50.0%|
|Avatar, 21 hits||50.0%|
|Bloodbath, 11 hits||50.0%|
|Dragon Roar, 8 hits||75.0%|
|Battle Cry, 7 hits||80.0%|
|Enrage, 6 hits||87.5%|
Depending on talent choices we can distinguish a few important cap points:
- 12.5% haste. We get an extra attack during enrage (very important) and avatar, if you specced it. I'd say this is a minimum to make the spec functional.
- 20% give us a boost on Battle Cry which is very important, and then the talents Avatar and Bl oodbath if you have them.
- 25% is the real number here, giving an extra attack during Dragon Roar. The extra 5% also gives some room to move for Battle Cry etc. Because of the short cooldown on Dragon Roar, you're bound to feel this difference.
- 50% which is a big jump. It's no surprise that 50% stands out. It effectively reduces the GCD to 1 second, and all buffs last an exact number of seconds. When slightly over 50%, all buffs grant 1 extra instant within the buff timer.
After 50% we see it becomes increasingly expensive to get additional abilities within the buff timeframe. Haste will still reduce the cooldown, making it possible to cast the same buff more often during the same fight.
