#Skillspeed reduces the Global Cooldown of Weaponskills.
#Skillspeed reduces the cooldown of certain abilities to compensate for that.
#Skillspeed DOES NOT reduce the cooldown of "No mercy".

this causes unclean rotations with 600+ Skillspeed (2.47 sec. gcd)

All BiS tankgear gets you above 600 Skillspeed.

Solution:
Skillspeed must also reduce the cooldown of "No Mercy" to be in line with "Sonic Break" & "Bow Shock"
