Detachment possibilities in 1k games

Assuming BW will be 3 DP, what are our thoughts here?

Also assuming existing detachments become 2DP... taking stock we have KDK, Goretrack, Possessed SB, and CoB. (with VoW becoming a 1 DP detachment focused on character models)

We are getting 1 DP detachments focused on basically Maulerfiends and terminators (of which none of our characters can lead atm...)

With 2 DP to spend, all of these seem to me a bit awkward to me to run in 1k as they are all hyper focused on specific units with limited points to spare. Combining two of the three 1 DP detachments seems even more awkward.

What are people's thoughts? Do any folks have experience running Goretrack or Possessed SB in 1k games for example?
