Unlocking nodes on a planet no longer gives mastery xp. Instead, players get a nice chuck of xp (1K) for completing the planet’s junction mission(s). I read this back when the patch notes came out, but I didn’t realize until a couple of weeks ago that players like me who unlocked all of the nodes under the old system will still get xp for the junction missions as well. I was already close to the next mastery rank, and running a few junction missions while leveling Titania was enough to bump me up.
I appreciate the fact that I don’t need to use a void relic to run a fissure mission. No prime part reward, but will still get void traces for completion. Makes it easy to farm traces, since I don’t have to use up a bunch of relics in the process. The next time I receive a 2x resource booster as a login reward, I intend to do just that.
