ROBLOX should add servers for parties,like if I'm in a party with some friends,it would be cool to press a button on the game page (like the play button) to play with people on my server only
Roblox has to run every server that is being played. This could double or even triple the amount of servers that are present at any time, which might crash the entire site. Roblox wants to run as least amount of servers as they can at a time.
