I would hope this is a bug, but nearly every piece of Tionese Imperial Agent gear has +Defense on it. It only seems to be Tionese gear, and it is not just Imperial Agent gear.

as does sniper field-tech gear

I, as a sniper, am able to use my Ballistic Shield twice on this fight, during the first salvo, and again on either the third or last salvo, depending on our DPS. This is on HM.

This is a very huge bug imo. Zoning to and from your ship with a companion crafting will more often than not instantly finish the crafting queue for that companion. Regardless of the amount of time left, there could be 40 mins or 4 mins, and often times i will get 2 items in my bag instead of, well nothing because it is still being crafted. I have two open tickets about this in-game with no response yet, and have only seen a handful of people talk about it. A quick google search will yield 'exploit' websites detailing how to accomplish this to flood the market with crafted goods. Bioware please fix this or at least acknowledge it exists.

Cybertech will make armoring and mods, and also ear pieces.

I am in the same boat as you. Half a bank full of BOE green light armor that cannot be RE'd as synthweaving.

I'm not quite sure that is the case with every crafting skill. As synthweaving, I have almost half my bank filled with random BOE greens that cannot be reverse engineered, mostly light armor, gloves, bracers, etc. They are items i can equip, have stats that are useful but not upgrades. But, the artifact and prototype BOE's i have found, that I cannot equip (medium and heavy), are able to be reverse engineered. Anyone else running into something similar?
