Continue to level JC?

I've played since the first day of hard launch and atm I have a max sid,lumi, 6* phasma, and I left JC at 5* to work on Kylo who is now 5* and halfway to 6*. I found that I can manage my GW battles which are more or less almost always level 60 teams after the first 3 battles are finished, the last six giving 5-7* purple geared teams. I'd work on geo after getting JC to 6*, he won't be much of a big game changer once that patch hits and he can't get better gear while other characters can. Geo seems to be a good solid damage dealer and he does synergize a bit with phasma with his Swarm attack (assist skill). I've also managed to place top 10 almost everyday with JC in my lineup although I'll probably be replacing him once i get the replacements up to par.
