So we have Diplomats, Skilled Spacers and Spynets. What do you think and why?
Diplomats. On the whole these feel weak. They can stop an assault on a non occupied planet. At best this might situationally deny someone getting a Spynet or Skilled Spacer of their own or it could deny an obviously useful resource planet.
Sk Spacer. I see value for these but I think moreso towards the latter stages of a campaign as fleets adjust and try to adapt.
Spynet. For me these are the most desirable as they can offer a fix to some poor setup choices or a chance to flank without response, and we all know how critical setup is to the outcome of a battle. Mistakenly I didn't grab one of these during initial setup of our campaign and I feel it will be punishing in the turns ahead if I can't get one.
