Future

Gearing up your FO is a good move, especially with EP 9 on the horizon. In terms of who to farm maybe start the DR farm

Separatists and GR are relevant, as are either of the Revans.

Going for FO can be hit or miss, as nobody really knows how the future will play out, and whatever ep9 stuff comes out might not have synergy with FO but have a new faction tag like Knights Of Ren or whatever.

Honestly I don't think there will be a FO meta, as that would probably mean stashing OG Kylo and KRU with whatever new Kylo comes out, and I don't think that's what CG would want. So yeah I'd hold off on farming FO, if they're gonna be meta then it will probably be with a new tag.
