Too many systems aren't the issue. It's bad connections. Why on earth Omicron Tau hasn't been relegated to the other side of the map and the T-37-Alpha link hasn't been rebuilt is beyond me. People say "oh well we made the distance shorter" - it's still an inconvenience and nowhere near as good as the connection used to be.
In regards to faction redundancy... I'll say the following:
Harmony has basically developed itself to overlapped HF - maybe even doing HF's role better.
Hessians utterly dwarf Bundschuh and whilst Unioners have made a push to make themselves more distinct, arguably all other Rheinland unlawfuls still play second fiddle to Hessians.
Mining bonuses being handed out like hotcakes to factions has undermined the speciality of vanilla/original mining factions and given them needless competition instead of keeping mining activity centralised.
A lot of Corporate IDs desperately need a bonus or perk of some kind to make them worth playing. People have said for a long time that groups like OSC should get a bonus for delivering people commodities to places.
I think people are starting to get the idea that this isn't just an issue with a faction's leadership or the player faction itself. Lots of factions desperately need assistance from a development perspective to become attractive.
