Dare I say, "Make Credits great again", nice thing would be to allow users to purchase Mats.
I great way to interduce a credit sink?
Nah.
that could only have two possible outcomes.
1) Mat's would be cheap enough to buy without issue (like refuelling/rearming your ship) and that'd render the entire engineering process redundant.
2) mat's would be punitively expensive and that would only shift the problem to finding ways to make sufficient credits to buy the mat's you need.
What
would be nice if some of those fancy new installations that FDev put into the game provided decent sources of mat's.
You find a wrecked comm's hub in 'goid infested space, you hack/scan a bunch of data-points on it while evading/suppressing the 'goids and you get, say, 20 G5 scans from each one.
You find an orbital laboratory that's well-defended. You have to shoot a bunch of power relays on the station (which makes the station and ships hostile) to bring down a force-field which allows you to get inside and shoot some cargo racks which yield a heap of G5 mat's.
You find an orbital military base, you attack it, shoot some power relays, open some doors, get inside and get to steal a bundle of other G5 mat's.
Implement that sort of thing and it wouldn't
matter if people choose to relog (or jump out & back) to farm it because they'd have to complete the required task to collect any available mat's.
