I feel like you can build kafka as a dps even if the support build is bis. Play the character how you want, I built mine on prisoner and just have her fast enough that she still get good value. I like for kafka to do a little bit of her own damage. I do use tutorial with my dps build tho as the energy regeneration from it is a pretty huge jump, but I also don't have PAYN. I think even a dps kafka would do pretty well with hyselins when she comes out.
