So... in leveling my char with Cybertech, I noticed that the skill trainer goes from grade 4 to grade 6 mods to teach me. No grade 5. Searching GTN, I see no schematics, and only a couple grade 5 mods. Is Cybertech not able to learn to craft these?

Cybertech armoring go up every number (4, 5, 6, 7, 8)

Cybertech mods go up every even number (4, 6, 8)

Artifice enhancements go up every odd number (5, 7, 9)

 

So every two levels, you can upgrade your armoring and either your mods or enhancements (alternating).

Ahh, ok. In a way that kind of sucks, but at least it answers the question. Thank you.
