It takes one mouse click at the start of the game session to avoid (in the same instance) PvP entirely - that's not "a great deal of effort".
Only if you're also avoiding Open, which is something I was never going to do, nor was it something most people, especially early on, wanted to do.
Which speaks more to Frontier's position on player choice (as to when to leave the game) than to a desire to make players stick around for PvP engagements.
I think it speaks to Frontier's apathy more than anything.
Regardless, pretty much all of those issues I pointed out, and a slew of others, degrade Open in general, not just the overt PvP aspects. They reduced meaningful player choice.
The block feature was introduced unasked before the game launched - as Frontier knew it would be needed - it's as much a part of open as menu exit and the ability to shoot at anything one instances with is.
The block feature's instancing weight hasn't remained static, it's gotten stronger. Anything that craps up instancing also degrades Open, PvP or not.
There's also the fact that until the fold-down of Horizons into the base game only about half of players had access to Engineers.
Yes, that was also a problem.
It was never there to lose - as no player has ever needed to play with other players to play the game.
I have utterly no idea what the logic behind that statement--which I find to be patently false--could possibly be.
You, or anyone else not needing to directly encounter other players does not in any way imply that the game everyone in Open had wasn't there.
To play the game I play requires at least the potential for encountering other player controlled characters and it requires the possibility for violence between those characters. NPCs sure aren't up to filling the gap, either in terms of verisimilitude, socially, or difficulty. The game I had was predicated on the myriad of encounters (the vast majority of which were non-violent, but still shaped by potential for violence) made possible through instancing with other players. Likewise, every new mechanism that has disincentivized Open, which is quite a few of them, has taken a piece of that game away.
