I agree that the registration needs to be opened. That's a given to have any chance.
As for the old maps? Guys, it wasn't the maps... I was there right before the new maps were released and I can tell you that the old bonfire and old ficho felt pretty empty at times too, maybe not nearly as much as the grounds does now but the point is that things weren't exactly better just because of the old maps. I noticed a huge drop from 2014-2016, the hacking was in the middle of that and caused a fair number of problems too. I guess what I'm trying to say here is that constantly hearing about how 'bad' the new maps are/were and wanting the barren older and far less detailed maps back, even from a player's perspective, just seems/seemed very silly. That's how nostalgia works really, you don't just miss any 1 thing about something old, you miss everything about it and getting only one thing, or a different version of the same thing, only to realize that that alone wont solve any desire would leave you with a "It just doesn't feel the same." feeling, you know?
It's not the fault of any one thing and if we hope to move forward, we all need to come to terms with that and create not the 'old' spark, but a new spark with new life.
