Kaya1 into call of the wild is a trap. She doesn't actually do enough for her battle group to justify it and I think you'll find her fury starved in that list without a good place to park occultation.
While not the best caster for it among our options I've found she works best in Dev Host or Wild Hunt. In both of those themes you can find good targets for occultation and she helps get the most out of her limited battle group with the +2 to hit limiting the requirement to use primal.
In Dev Host she can occultate a unit of ravagers or bloodpack and then leverage female tharn to deliver an almost 100% stealthed list. Also the spirit door then doppler bark trick can enable big ranged assassinations with the bloodpack or blood trackers. Its quite difficult to hide from that. Ghetorix and a stalker help cover the armor cracking for the list.
In Wild Hunt she can occultate a unit of skinwalkers or wolves of Orboros which helps cover their biggest weakness and the doppler bark trick can really help reaves seal the deal on an assassination run. Kaya can also charge doppler bark and then spirit door out to help bring down high def infantry.
If you really like the character and want to stay in call of the wild then I would recommend Kaya2 or 3 for that purpose.
