KD'ing first 2 bosses in Asura

[Update]

So as the title says, is it possible as summoner to kd Gen & Ken?

Everytime I use one of my KD spells (Thorn strike specced on KD, Beckon specced on KD or Anklebiter/Suprise Gift) it keeps 'resisting' and they wont KD.

Any advice?

[TJXX]

Thorn strike and Anklebiter work together.  Make sure they don't have their CC resistance up.  (Full white bars.)

[Bits]

Don't use Beckon (E), as the KD won't work as a joint attack. Use Thorn Strike and Anklebiter, make sure their white bars are gone, and you have to hit them before they start to spin, as they deflect attacks while spinning.
