With 1.6 the AI now surveys the Ship Graveyards and Precurser Anomalies. This is good.
However they don't have to fight the guard ships and can survey with an unarmed survey ship. This sucks.
But it does beg a question.
Why can't we see the ships guarding the Graveyard/Anomaly on the map or when we click on the anomaly?
I've said before that the Percurser ones should be guarded by a significant force so that these are Late game prizes.. currently two small ships with force fields and Harpoon missiles can take out the "heavily defended"
Honestly we should be able to see who is guarding things and have different levels of guards and thus different levels of "prizes"
But that's just my suggestion.
