Personally, I really like the Engineers and the modifications they make. I do love exploring, but it's not the only thing I like to do in the game - I like to try a bit of everything.
Therefore, once I'm done exploring the Formidine Rift area for now, I'll head back to the Bubble (probably after 2.3 drops), sell my exploration data (being careful until then because I have a tendency of exploding in the Rift area), have fun gathering the materials (I don't tend to grind or farm mats, and I enjoy the new places and experiences searching for materials gives me), make my upgrades and probably head out somewhere else... might even try my hand at the Ancient Ruins puzzle next and see how far I can get.
I have found that if you don't drive yourself crazy trying to get the absolute best of everything as soon as possible, everything becomes a lot more enjoyable. I haven't unlocked Selene yet, or indeed, very many other Engineers. Every so often I'll fancy doing a bit of mining, and I know one day I'll get to the 500T unlock requirement and be able to work towards strengthening some armour, but I'm in no rush for it.
So yes, I am happy with the extra Engineer mods for the scanners and sensors. They make sense, and they're going to be helpful, and I'll probably prioritise them, but I'm not really in any rush to get them. Gotta unlock Tiana first! I sure as hell ain't Elite yet, so Lori Jameson is out of the question.
