I'm not nearly as up-to-date on Necron fluff, but I get the impression that mobility isn't especially vital to them either way, since they already have overwhelming force in dormant bases scattered around the galaxy. The Necrons don't need
to spread out to conquer, since they already have the setting thoroughly 'occupied'. The younger species just haven't caught on yet.
