I’ve been progressing my Technomancer nicely with some help from @Brave in places. Just ready got the briefcase so opened up the travel to the next section but got a couple of side quests to run through - including No Place Like Home! The last section I did was pretty tough but worked out what I could be doing better and got through it.
Also read what I hadn’t noticed before that the world levelling is based on kills without dying, not simply progress - which is actually really clever. So the world level-up doesn’t happen/become available until you are comfortable in the current level.
Upgrades, dismantling etc looks suitably deep, nice and not too obtuse (cough Destiny 2 cough).
