As the Omicron Update is still MIA, in the next patch Omicron Zeta will receive a set of changes in order to improve server gameplay as this system has been a severe pain for a large amount of Omicron players. Nobody really wants to fly 200/300k to encounter a player.
The general layout has been severely shrinked, halving travel times in general. Mu JH<>Delta JH and Rho JH<>Delta JH have been reduced to ~30k. Nomads have been brought closer as well as the average distance from Iota's JH to any other in Zeta is between 30k to 40k.
Rho/Delta/Mu/Iota JHs have been placed relatively close to field edges to avoid problems with capital ships stuck in rocks.
Do not build a POB in Zeta until the update, otherwise your base will end up most likely anywhere but where you'd like it to be.
