Yes, i am on it atm. But, as i see, the same problem with hunter pets. They scale with haste from hunter items, but doesn't scale with auras that give haste. Also it's not dynamic, it's calculated only when you call your pet. So it's global bug.
From today we have one new developer that will work on PVP bugs (spells, talents, mechanics, glyphs etc) - DeadMouse.
On days he will start working on bug reports from the forum.
