When creating a hair particle system most brushes have a strength default value of 50 or 100. With that strength the comb brush behaves almost like the cut brush.
Seems to affect: Comb, Smooth, Length, Puff, Cut, and Weight.
**Exact steps for others to reproduce the error**
* add a mesh
* add a particle system to mesh
* change type to "Hair"
* switch to Particle Edit mode
* click "Comb"
* look at Strength input field
