Hello ANet,
I recently found a bug in two of the Beast mastery blue major traits ; Commanding Voice ( Reduces recharge rate of Pets F2 Skill by 20%) and Speed Training (Reduces recharge of Pet’s skills by 10%).
The bug is that they do not really reduce the cool downs of the skills.
However it did work pre-patch.
Note that I have tested this in SPvP in and out of combat. Please fix it!!
I hope this helps
