With recent frustration in trying to find groups in D1 (yes, I, like many others, still play it) I decided to make a solution. I threw together a no-frills, straight forward Discord for D1 players to form groups. It is set up pretty simple and is open to all platforms.

Disclaimer. This is not a recruiting post, I am not looking for a clan and not recruiting for my current clan. I have no benefit in doing this other than other D1 players populating the server and making easier for all of us to do D1 fireteam events.
