I've seen mention of an Omicron system revision so perhaps that will make my post redundant.
Regardless, I believe there are multiple incredibly boring Omicron systems on the very upper region of Sirius; specifically the 80s series. I don't currently have a character that has that region charted properly nor one near there, but from memory they were 80-82. Flying through those systems felt unfulfilling as they seemed to be placed there for no reason other than to expand Sirius. They seem for the most part bland and unneeded. Hopefully this can be changed by adding objects of interest or combining the systems or something. I was semi-conscious at the time due to being awake for ~34 hours so that of course could change my view of it. I am also not taking into account the potential 'strategical' value the systems might have for OC and/or the Frenchies.
With the Greek lettering Omicron systems there are two entirely separate paths through them. If you are on one there is no way to get to the other without returning to the fork. This makes the systems somewhat awkward to move through. I understand this was probably done to increase traffic in Hispania cap worlds (conveniently being the two forks on either end) but it does feel quite uncomfortable to move through the Omicrons because of this.
Kansas really is a one trick pony right now though. Perhaps that was deliberate?
