Turn rate

Turn rate is the speed at which a unit can turn. Every unit has a base turn rate, which can be lowered by some abilities. The vast majority of heroes have a turn rate between 0.4 and 0.6.

Turn rate is expressed in radians per 0.03 seconds. A 180 degrees turn is the same as π (3.14) radians.

0.03π divided by your turn rate equals to the time it takes to turn 180 degrees. A turn rate slow is directly applied to your base turn rate. For example, a turn rate slow of 70% on your 0.5 base turn rate lowers your actual turn rate to [0.5 * (1-0.7)] 0.15.

(0.03π / T = t, where T = turn rate and t = the time it takes to turn around).

Examples:

1) A hero with a turn rate of 0.6 takes roughly 0.157 seconds to turn 180 degrees. (0.03π / 0.6)

2) A hero with a turn rate of 0.4 and a turn rate slow of 70% takes roughly 0.785 seconds to turn 180 degrees. (0.03π / (0.4 * 0.3))

3) A hero with a turn rate of 1.0 and a turn rate slow of 70% takes roughly 0.314 seconds to turn 180 degrees. (0.03π / (1.0 * 0.3))

4) A hero with a turn rate of 0.4 and turn rate slows of 70% and 50% takes roughly 1.571 seconds to turn 180 degrees. (0.03π / (0.4 * 0.15))
