Change Discord name to in-game nameSuggestion
This would make life SO much easier if it was a possibility
It doesn't look possible with the capabilities of the discord extension

This one does it and is the only reason I haven't switched everything to Discord Core yet.
We use Discord Auth and Sync for the players and Core and Chat for the crew.

How is it stability wise?  We had to get rid of all DiscordCore stuff (core, groups, and Core Roles).  I don't know what the issue was.  No errors.  But in a YEAR we have had 2 server crashes ever.  We had 3 in just 4 days of running Discord Core stuff.  And the reason it was 3 in 4 days is because I uninstalled all of it for 24 hours, and not a single crash, put it back on and a complete server lock up (like froze completely not even a crash and reboot).

Turned them off and not a single issue since.

DiscordAuth and DiscordSync works fine although I have it set to reload every 30 minutes with TimedExecute, otherwise the extension/Discord bot closes the connection and the bot goes offline.

I have no issues with DiscordCore, and I use DiscordChat so the crew can help the players in game chat without having to log on to the server.
That said, I haven't used DiscordCoreRoles because of the lack of name sync so I cannot attest to the performance/stability of that.
I do like the compartmentalization of MJSU's plugs and we use MagicPanel as well with great success.

Support for name sync has been added in version 1.2.0. You will need to be running Discord Core 0.16.0 in order for it to work.
YEah I LOOOOOVE MagicPanel.  I just cannot figure out for the life of me what the performance problem was?  Maybe because we run Rustcord too?  I don't know.  All I know is after experimenting the DiscordCore suite was definitely what caused our issues.  Without them we've been running for a solid week now at 150 players online with 92 plugins and a huge custom map and the server has been screaming along at 80+ fps (capped at 90)
