Now, before you call me crazy or a troll hear me out. Compared to Sprint from rogues, Cheetah is woefully under powered, and I can prove it.
Now, I don’t know how fast we actually run in game, but for simplicities sake, lets assume the default speed for everyone is 1 yard per second.
Sprint is a 70% increase for 8 seconds, with a 1 minute cd.
Cheetah is a 90% increase for 3 seconds and a 30% increase for 9 seconds, so a 12 second speed boost, with a 2.5 minute CD.
So let’s do some calculations.
Base Speed: 1 x 8 = 8 + 4(to even out with cheetah) = 12
A 70% increase in speed means with sprint a rogue is going 1.7 yards per second.
With Sprint 1.7 x 8 = 13.6 + 4(to even out with cheetah) = 17.6
So with sprint a rogue will travel, assuming a speed of 1 yard per second, 17.6 yards over 12 seconds.
Now lets do cheetah.
Base Speed: 1 x 12 = 12
A 90% increase comes out to 1.9 yps and a 30% increase is 1.3 yps.
With Cheetah: 1.9 x 3 = 5.7
1.3 x 9 = 11.7
11.7 + 5.7 = 17.4
So over twelve seconds the hunter will actually traverse slightly less ground then a rogue when using their speed boosts. But, factor in the length of the cooldowns, and a rogue can use sprint 5 times for every two times a hunter can use cheetah.
So in short, in comparison, cheetah is underpowered compared to sprint based on the length of the cooldowns.
