Diplomacy towards both has not jet been defined and can be assumed correctly as neutral.
I would greet any sort of RP interaction to help defining more diplo,
and would react with either FynnMcScrap or Mr. Tukker, whatever fits best.
Till we manage to get official and get a chance to obtain a rephack with the official ID ( Tinkers ID ) I use all chances to define the rep. And will greet balancing suggestions or feedback accordingly :-)
Edit : actually we have quite a few IC ships at the Haven currently, as they can buy Scrap with us and H3 with Shuri. So far no official contact.
As for AI : Kudos to the lone AI cruiser "Angsthase" , coming to the Haven to sniff in our stock, I enjoyed that RP ;-)
