I have a similar deck as yours. The only difference is that I have Chiro instead of Gatline. It actually depends on which clans are mostly used for the week.
I have Jane Ramba but I still use Nahomi to support Chiro. Assuming that I have Chiro and Nahomi in my hand and my opponent is using GHEIST/Roots, then Chiro would only have 4 damage but would have 8 power. On the other hand, Nahomi would have 10 power. In this kind of match, you would not really want to K.O. the opponent; you would just want to win rounds.
If I am not fighting against GHEIST/Roots, and again, assuming that I have both Chiro and Nahomi in my hand, then I would aim for a 2 hit K.O. or you can use Chiro to bluff and make your opponent overpill.
