And, you could also use this for preventing engine techs, no?
It's definitely going to need an FAQ, but my first thought is no.
Why would it even potentially prevent engine techs ( need faq) engine techs are not dependent on speed, just the command ? If I had changed my speed to 0 last turn and I had a navigate dial or token I could spend the command for no effect, stay speed 0 then use engine techs to make a 1 move, but still be speed 0 for next round..... Not sure why I would, but I could.
I agree, which is why my first thought was no, but I'm not going to commit to a position without having thought through the potential arguments against my initial impression.
Do you not "Determine Course" when you Engine Tech? (I have no idea what the correct answer on this is.)
