I dunno if this has been mentioned, but I'd like to bring up a respec option I've seen elsewhere. Respecs themselves aside, this other MMO had a Respec "Mirror". Basically a device placed in your home (ship in this game I suppose) and you could store a copy of your spec in it. Then run to the Respec NPC to respec to something totally different. To swap back, you ran home, used the mirror and it swapped your current spec with the stored one. No cost for swapping back and forth, but if you wanted to alter either, you had to go to the respec npc again and deal with whatever costs were involved. I usually had a group spec and a solo spec. Some folks used it to test tweaks. Here it could allow for a PvP and a PvE spec, or whatever. To build in a cost it was a crafted item. It took effort to be able to craft it and it took a significant investment to get one made (rare/expensive materials, etc). IOW, cash sink. Make it a cybernetic implant with a time restriction on it or something. Make one of the Kolto tanks on the ship "recondition" you or somesuch. You could even put a timer on it like sending your companions on missions to prevent people from doing it "on the fly". Anyhow, not an original idea, but maybe someone more creative can find it useful.
