First Order Tie Pilot Zeta?

I presume his zeta would increase his crew power in ships so could be useful

I wouldn't zeta any pilot just for the ship unless I absolutely had to eke out one more point of speed and I knew the zeta would do that - it wont necessarily.

You have six saved up for SLKR already? If not, I would save up for when you unlock him.

As far as his ship goes, FOSFTP's ship is generally more useful with Finalizer in the current meta. That leaves FOTP as either a reinforcement or part of a mishmash leftover squad.

There are probably better places to use the zeta, especially if you don't have the 6 for SLKR like @LordDirt said.

Eh idk, with KRU lead my zFOTP hits for like 40k at basic, twice, so i think it's not bad.. as a toon i use him more than FOX since his double taps deals significantly more damage than FOX at the same gear level.
