This is good. Though couldn't we assume the vex would have multiple planet minds to calculate each section if our galaxy. They seem to have endless reach and as the ghost says "they can warp across start systems in an instant" so why bring that up unless that's something they often do. With even two or three more.mind planets they'd have a far stronger advantage over us and any "third party" forces Ex: fallen, cabal, hive.
Also, to add on, they do use Cyclopes as relays. And the individual units use select "axis minds" to do all the coordinating of groups, be it builder, infiltration, or assault team.
