A little thought here…
What if there were not only Conduits and Portals, but ‘Links’.
Thinking like -
Conduits as single use, as they are already.
Portals for inter-planetary, charged with Oort shards, basically current Portals.
‘Links’ which would be for intra-planetary only, these would be limited to 1 per 10 levels or something?
This way hubs would mean more I reckon. Tagging @Xaldafax since you’ve been thinking about this a lot by the sounds of it
