Grade 5 in one area wouldn't directly help, since research is per-module.So my question is, why would anyone use the engineers? I can fly back to the bubble in the same time as it would take to collect the unlock requirements.
Why not make them grade 5 for one area and 1 for the rest? That way they would get used and then level up?
A few reasons I can think of for them to be useful and attract help even at G1 (all of which I've used them for)
- you can only have so many pinned blueprints, and you might not feel like flying all the way back to the bubble just to engineer a lightweight limpet controller. G1 still saves a bit of weight, so why not do it?
- a few blueprints (e.g. long range railgun or laser) you get almost all the practical benefit of it at G1 anyway
- you're using pinned blueprints anyway but you'll put G1+experimental on at the local engineer first to "do your bit"
- 44kLY round trip is a bit far to go to get engineering done if you don't like travelling and you'll just put up with not having maxed everything.
