One more option to consider:
You keep reharsing the same table, with minor tweaks here and there, but keep failing to acknowledge and/or address the main problem.
I'll try to make it as simple as possible, hoping that even you can understand it.
Generally, attack fleet speed is a major factor in a player's choice. During a merge, a player would want to stick to the same speed, or stay as close as its original speed if the previous option is unavailable. Not convinced? Just look at the tantrum that ONE single players is throwing about the presence, or lack thereof, of a 5x speed option. He consider even a 4x speed as unplayable, go figure.
Now, with that in mind, here's what happens with players in Group 1:
Group 1
Exodus: Vega, Lacerta, Thuban, Fafnir
Target: Universe 1, New A, New B, New C
Fafnir: NewD is an almost exact copy of Fafnir, main difference is 2 galaxies more. Check.
Thuban: NewB is an almost exact copy of Thuban, main difference is it gets to 9 galaxies. Check.
Lacerta: NewA is an exact copy of Lacerta, down to the number of galaxies. Check.
Vega: only option to keep the same fleet speed is to forego ACS and being crammed into 5 galaxies. Fleeters will be unhappy because... D'UH, no ACS. Miners will be unhappy because all the spot 8's will be taken in days.
Do you see the problem now?
Things like higher debris field ratio or lower deut consumption are just sugar pills meant to sweeten a turd sandwitch. Players don't care much if df% or deut% are different, they care about ACS, or lack thereof, and the ability to settle on convenient spots.
