I'm well aware of how they function. My primary issue is with the fact that they, unlike every other race, can't have their settlers utilize their ley-lines (ideally to clean pollution and late-game quickly make the settled lands.)
Ideally I'd like B units to use ley-lines. Can you modify either 'flying' or 'roads?'
Alternately: Is there any way to bump their movement based on tech? Upgrade-able to a new B Settler with higher movement linked to the tech? Might at least confer some balance to the change...
