Well, if colonia enginners improve if they work, why the bubble ones don't?
They (Bubble Enginners) have some mental problem that don't allow they to learn?
Think of 'em like car mechanics.
Alfred Buchi might've
invented the Turbocharger but you'd probably get a better result by going to an outfit like TurboTechnics to get your car tuned.
Same thing with engineers in ED; just 'cos one of 'em was the first to offer a specific mod', it doesn't necessarily follow that they'll always be the
best at performing that mod'.
Not entirely sure the engineers in the bubble need much of a "buff", really.
I don't think they're lacking in anything major, if you're prepared to put the effort into visiting them.
About the only things that might need a tweak are somebody in the bubble to offer G5 SCBs and Life-Support.
The biggest change I'd like to see for the bubble engineers would be to pick 3 or 4 "main" ones who, between them, can supply every XFX in the same way the Colonia engineers can.
That'd mean players could get all their XFX applied just by visiting 4 engineers instead of having to schlepp around nearly a dozen.
