With Diminishing Returns, how is stun locking viable - especially if the target has a trinket to remove the initial stun?  From what I understand, Cheap Shot and Kidney Shot are both in the Controlled Stun category.  I would think that if the initial stun from CS were broken, you'd only have two - maybe three - CP's, which would translate to 1.5 or 2 seconds of additional stun length with KS.  That's not much of a stun lock...
And the break in stun could be a fatal one depending on the target's class/build.

 ) get a restealth off and open again from a position of strength. This isn't even factoring in blind x2, vanish x2. Warrior resists your Kidney Shot? Can't gouge him? Blind him. This is all subjective to what you're fighting against as well, keep that in mind.
