I think to be succint, what Rubbernuke is referring to is that in a element of the game which is PvP/TvT, all players need to face the exact same level of risk when conducting actions relating to that, because otherwise you end up in a situation where the Solo mode AFK Turretboat and Netflix-and-haul Merit shipper king, leading to (i) a feeling of unable to make an impact for the 'Joe Normal' player who doesn't leave their PC turned on parked in a CZ while they go to work and (ii) a lack of need to interact with/engage with those players who are supposed to be your teammates or potential rivals.
Except you have to look at who is doing the arguing, its those who would be facing less risk. Its an argument made in bad faith. Now, if it was haulers making the argument, i'd say its a valid point (and i do appreciate you, with your name, making the argument), but look at the Kumo crew members who are doing the arguing. They won't face increased risk, just more targets, while they sit as safe as someone in an AFK turretboat in solo.
Speaking of AFK turretboats, that is an issue FD do need to look at, and its an issue of their own creation they enabled with HP inflation, something i've criticized myself on many an occasion.
As for netflix and haul (not merits with PP2), what's the problem? People can do that if they want and since they will be affecting PP2 via regular activities, based on what we understand, its basically a call to say that people who are pledged have to always play in open. They would have to be blocked from choosing PG or solo, because it sounds like almost any sort of activity can affect PP2 if you are pledged.
This would make the basis of this thread have to be "Open only if you are pledged", meaning any time you are not actively pushing PP activities, let's say you go out exploring for a while or just want to chill doing some missions for credits or materials gathering, you'd have to either do it in open or unpledge to get access to PG/solo again, thereby losing your rank and all bonuses.
That's a tough sell.
