I don’t believe you have any evidence for how many players fit the “parasite profile” you describe.
Until you do, all that can be said is “It’s likely some parasites would stop playing EVE”, but it can’t be quantified.
BTW in case you didn’t see the earlier posts: my suggestion is that each player using PLEX to play should pay one “player month” per month. I.e. not one per account.
I see what CCP is doing with PLEX. Since there are players who will pay RL money for ISK, it makes sense for CCP to find a way to get as much of that that money as they can. PLEX is better than Skins, but it’s not perfect
But that’s not why I started the thread. I thought it would be interesting to look at possible changes in the way money moves between players and CCP, but excluding microtransactions.
There hasn’t been much of a discussion, but it’s been interesting in other ways
