MACO gear is good stuff, as crit is king in ground combat.
That said, the fleet armors are excellent. Get a fractal demodulator and you're fine.
**** some of my toons run with Chrono armor ffs!
I keep my away teams stocked in Fleet Gear. It's really the best for away teams because it doesn't rely on any power procs that AI is too dumb to use and the fleet shields/armor are great for keeping BOffs alive.
