People keep wanting to make colonization a squadron-oriented feature that solo players can dabble in. It is not. It's a personalization feature that squadrons can use to influence BGS play. One architect launches the beacon. One architect has authority. One architect collects profits and pays taxes. "Your new empire" is the tagline. Variations on the word "you" (you, your, etc.) appear on the Trailblazers page 47 times. The word "Squadron" appears once in reference to the token connection to BGS gameplay. Colonization is an individual play feature. The squadron-oriented feature is coming next (and could conceivably link with colonization in a few token ways from within the Vanguards UI, one might suppose, as in setting a squadron goal of completing X construction in X system...).
I would love to see the tether removed and leapfrogging to be prevented in terms of making the feature suitable for building remote bases for exploration, but the game-lore goal of colonization is expanding human territory, and FDEV has already stated that rapid expansion of the bubble by leapfrogging player colonies is an intended design of the feature (
