Big changes are on the horizon for EVE Online in the Dominion expansion and beyond. Alliance sprawl in 0.0 security (lawless) space is going to be curbed, in favor of a new paradigm where alliances claim less territory but can derive much greater value from what they hold sovereignty over. This is the focus of a dev blog from EVE Game Designer CCP Chronotis -- "The Streams Must Flow".
Streams in this case refers to EVE's various revenue streams which are going to be altered in the coming months, and how this will affect players in 0.0 alliances. In the past, supporting a large number of players required an alliance to draw upon the resources of many different solar systems, specifically high-bounty pirate NPCs and valuable ores in addition to a very high passive income from rare moon minerals. CCP is adjusting how those rare minerals are used in Tech II production, meaning more common materials will be used, so Dominion will allow alliances to upgrade their controlled space as a means of generating more income.
