Cryx Scavenger - is it worth it?

Just got my hands on the latest NQ (#35) and among other models spoiled, the Cryx Scavenger bonejack was one of them. It cost 4 points with typical stalker stats. Abilities include Finisher (ref. Gerlak), Flight (ref. Angelius) and Sprint (ref. Strakhov).

I'm now considering getting this jack once I expand my Cryx army (soon).What do you think of this jack? Is it worth it?

Sprint seems interesting but the lack of parry is slightly disturbing. Combine this with Flight, I feel this little jack is sorely underestimated. I see a stalker as a solo assassin and this as a heavy infantry/light jack killer. Surely with the ample corrosion opportunities Cryx has, finisher is bound to take into effect!

saw it and i felt hard to play unless denny tier list is involve .1 defiler 2 ripjaw and 2 scavenger .basically rellying on defilers and denny venom to play him perfectly though

dunno man. i have mix feeling about this birdy. feels like u have to spend alot of focus on a bonejack... doesnt sit too well with me.

i guess it could combo with ripjaw.
