Yes, there is a Legacy Perk you can purchase, that will allow in-the-field respecs on a cooldown. There is also an in-the-field repair droid you can purchase, which is just as helpful.
Good to know. I didn't bother to look. I'd rather see dual spec though.
As for operative, you can hybrid med/conceal or something for both some dps and heal and with modest purples can heal most HM's that way and still contribute to dps if your team is strong. Hybrid is great in pvp too. Expect high end end game to be full med though. Hopefully some top tier talent and core skill rotation changes come to concealment and lethality though someday.
