I didn't read all, want only answer to the first Post here.
* Local chat (station / system) OPTIONAL!
Station: all fine with that, possible with a short Range around the Station (in the same you must be for req. Docking for example).
System: no, that is too much, too far, not immersive.
* Job specific global chat (trading, bounty hunting, mercenary, exploration)
Hell no! This would be global Chat Channels > Players use it as General Global Chat and ruin it / Also Gold Sellers are very Happy to have such Channels.
And it make absolutely no Reason why a MMO should have any sort of Global Chats. It ruins the Immersion to Chat with every Player even when he is on the other Side of the Universe. And too many Players use Global Chat only to Spam, to offend other Players and other Things that ruins the Game Community for ever. I played MMOs since over 10 Years and I know very well from what I talk...
What a MMO should have is a clever Message System and no 08/15 (bog-standard) Chat System like the last 10+ Years in MMO Genres.
My Ideas for ED:
1. A Mail System for longer Text/Voice recorded Messages (Global). The Time they need to her Destination depend on the Distance between the Players.
2. A Messenger/Voice Chat for short Distance Communication (System). Like above the Distance of the Players set the Delay at the Communicaton, but here only very short.
3. A Bulletin Board (Forum like) on the Stations (synced with all bigger Stations from one Fraction) where other Players could leave Text Messages for some little Credits (to avoid too much Spam).
4. A Local Station Chat with Channels for Trader, Explorer, Hunters etc.
That are old Ideas that I had already 10 Years ago in similar Form. This would match very good into the ED Game World itself and is immersive in that Way, a simple 08/15 Chat System didn't.
* Guild / corp / wing features and chat
Could be sorted into my Ideas easily.
* Parties e.g. spontaneous small groups of players
Agree, should we have now with 3.9?
* Cooperative multiplayer missions
Not a bad Idea, like it. They are completely optional so no one must do this Sort of Missions when the didn't want it.
* Shared bounties in wings
+1
Whats behind that?
* Trading between players, credits
Hm... risky... that need a very good System or we have Problems with Gold Sellers that ruin the complete Ingame Trading System...
* Locating friends and party members on radar / map
Good Point, +1
