I recently got a damaged syn in the loot from one of those orbital freighter missions. Those missions are brutal! Lost a few gals and everyone else came back wounded. Lots of fighting in those grav lift shafts. Anyway, once I did all the research and rebuilt her, I find I'm having trouble finding the best way to use her.
The high TU, energy, and good resistances made me think melee, but the poor energy recovery and lack of inventory space for recovery consumables made me think twice. Same problem for a dedicated thrower/bow gal. Currently I'm using her a high mobility sniper, so she only needs to move a handful of times, then can sit and snipe while the energy recovers. It works well, but I don't think it's really using her to her fullest.
I'm curious how others use them
