I figured I'd throw this up here to get some feedback and show a different angle for running Feng and Kaeris. I've only had a couple games with them, and so far never together, but I've been looking for a good excuse to do some renegade steamfitting and this seems like a good way to satisfy that.
Mei Feng (7ss)
Emberling
Kaeris
Kang
Johan
Fire Gamin
30ss total, for 35 I would probably just add another fire gamin and bump the pool to 8, but I do like rail workers and could add one (or two, if I'm comfortable with a 6 pool and don't like how the gamin performs) of those instead.
Basic concept is a strong melee lineup with ranged support from Kaeris and the fire gamin (and I suppose Johan, if necessary). My only concern is its lack of mobility, as Kang and Johan almost always need to be together and Mei Feng would do best hanging out with them as well. Kaeris, however, could use her wings to run around on her own. Even if the enemy decided to focus her, she's fairly resilient with a large pool, armor, and high damage output and any time they spend going at her is time for the others to take care of business.
