So, I left about a year ago just before season 1 hit.
Back then, you could only train certain T3 skills (like sensor scramble 3) if you had 9 ranks in sensor probes and were a science captain. As I was an engineer flying a science ship, this didn't work out well for me as I couldn't unlock half the cool powers. There was also no way to trade Boffs once trained so I couldn't ask a science captain to do it for me.
I know cryptic said it was on their 'to fix' list, but what did they do about it? Can you now trade Boffs? Or can engineers now train science skills?
