Used to be alot of action in Bristugo Connie so I checked why its all moved to Kion...
Bristugo has 2 Connie one takes 10% and the other one at the Vault takes 5% Surcharge
Both are empty and almost all commerce is in Kion Connie and that one takes 10% The rest of the commerce is in Clearport main connie that takes 5% So we are waisting coin by using the 10% Kion connie as our main
Edit: Bristugo 5% connie has Vault so BIG advantage AND Bristugo connie has a portal central just outside
