I am a purist I guess
Gamespace is gamespace and gameplay is gameplay. If some players have access to a gamespace/gameplay then all players should be able to access that gamespace/gameplay post game.
Specific to soah 's point. In a game space designed for game play(aka wolf chat), it is fundamentally unfair to withhold communication post game between player slots,. For example, you play a game with player b and me. Player b is your wolf partner. Now, in future games, player b and Soah have a competitive advantage over me at reading each other. Simply because they shared a game space, from a game I was in, making game play decisions, and I didn't get to read it.
I don't think it is something that MU needs to control, but I think an ideal situation would be the community having the standard expectation that wolf chat is released at end of game and it is stated in sign up.
The rest of the objections are focused on not wanting to have to worry about being to personal in a game space. I find them rather specious but I understand the sentiment. Honestly if a host said wolf chat is being withheld to protect an individual's privacy on the rare occasion it was necessary I wouldn't mind at all. However, protecting wolf privacy is actually the opposite of competitive fairness.
Pure game is best game.
P.S. I think this is something that site culture should dictate. I would just prefer it to become the standard approach.
