Well Sandro and underlings saw its future as something different.
I agree with this one. Sandro claimed that the aim of PP (unlike the BGS) was to supply a consensual PvP community endgame. You can see that all the way through the design. The reason for the Leaflet Deliverer (The alleged Postman Pat Simulator) is because there must be a bottom tier which the rest of the game can prey on and everything else is built up from that. The issue is that no-one who plays the bottom tier is in open because they get interdicted all the time, so they flip through to pvt or solo to make the deliveries count (Because the PvE enemies are not as good as the PvP ones), thus defeating the purpose of the game mode.
As I've said before, they need to move PP into open only and make the PP rewards available behind the tech brokers for people who can't/won't play in open. If the game mode is broken because of the promise that all game modes (open, pvt and solo) count the same, then the game mode must either be removed or it really has to be altered so that it's fixed.
When this was proposed, there was too much panic from the community that meant that CGs and the BSG would be only counted if they were performed in Open Only as well. I understand that that would be a step too far, especially when you count players who can't/won't get into Open, because there isn't a way to compensate players properly in those circumstances where you could in PP if you put the rewards behind the Tech Brokers.
Problem is. We've been going around this issue again and again in the time since Sandro proposed the change to Open (How long is it? 18 months?) and nothing has been announced or even hinted at. So I'm coming to the conclusion that PP is being left to whither and die. At least with CQC Discords, people can arrange matches and so that game mode can be kept going, but as far as PP is concerned, I think it's RIP.
