so as the subject says.. i am a little uncertain as to what to do next ..
i just got my 2 extra npc from the Zolazin chain ..
and from another post i know you can get 2 more slots from the :
"5th mission in the Lazuli Chain (starts at rank 190) called Tracing the Shipments give 2 Tevrazon Tracers for 2 more NPC slots"
i am still a while away from rank 190 .. so in the meanwhile which missions should i do? any suggestions ? which rewards / ship mods are worth getting? or which chains would give good xp?

Especially if your a pvpier do the mylarai chain for the kalviums i wouldnt suggest going the race though unless your gonna change later on cause mining aint all that important.

IMO:
aeon moon chain for flux and temporal orbs(120) unless u can afford buying fluxs
Gentarr chain for transmitters, energy never hurts. take the convoys as a bonus
I would at least farm out one galviz device from zolain battle, u don't have to do it now but u will likely want it eventually so if you got nothing else~

i always perfer to always keep 1 or 2 bio vips, mutagentic, a couple CCM and a paradox close at hand just in case, thou some perfer to leave the missions be to avoid random temptations but..... should there ever be a planet war, I perfer not to be caught off guard

and ofc... if u r willing to pay for it, defintely get mission exotic and dyson. unlike rift, there is no benefit in waiting on those

I'm a bit confused at what you want thou.... you are unlocking NPC slots yet you are using mission to rank~ so I can't really see your play style... so i guess that's that~

oh, if you can get ur hands on enough flux probes, do Kronyn chain plz.... The better one, IMO, being taltherian doesn't need any arti but... thou it unlocks at 230, which you might reach soon, takes ~100 ranks to complete... so in case you are waiting for that race, it's not really happening anytime soon so~

my play style? its a little random .. i do a little bit of everything.. 1 day some pvp another day alittle bit of missioning and another maybe some npc'ing...

but those Kalvium Fortified Plating looks preety useful so i think i will be going down that mission for the time being.

the kalviums are indeed usefull the only hull "modules" i have on my ship are things i got from missions / NPC / base attacks, and the kalviums are adding an additional 400ish hull EACH. cant wait to see what my hull will look like once i get around to installing researchable hull
