COMPARISON:

legacy server browser shows always more..

Since DOI playerbase is smaller than INS http://steamcharts.com/cmp/447820,222880
It's even harder to fill community multiplayer server especially as long as they not use regular playlist.
The ranking system is only enabled for NWI playlists which are restricting map pool to stock ones only.
I guess this is mostly why people avoid custom servers they problably prefer a xp rewarding experience to unlock stuff than a richer one with custom maps.
The other issue is how is designed the main menu, on INS custom servers for both coop & pvp are in the layout from playlist selection, on DOI it requires to 'browse servers' (i m not talking about legacy server but the ui tab)
that's why even during steam free week end (almost 10k players) custom list was still empty for pvp.
The solution in my opinion should be remove 'Casual with Bots' (Practise mode offer similar thing) and replaced by 'Custom' playlist & keep 'browse servers' (ui/tab) for total conversion only which comes with their own playlist.

On the other hand NWI try to highlight community made content:

and provided dedicated servers to community driven total conversion (Born to Kill:Vietnam, Screaming Steel,..) and maybe in the future for Broken Country 1936-1939!

I won't talk about sv_pure or motd removal because it's an another thing which involve hoster,player & nwi.

As you may imagine custom PvP is an utopia with DOI current state better wait for official events (steam sales nowadays mostly..), but custom COOP still remaining.

if you plan to play stock maps on official playlist there will be enough active players/servers with playable ping.

If you plan to buy it for extra-life / community made content then you will be disapointed.
the main problem is how is setup default main menu UI, quick connect > browse playlist atm which is mostly why it is dying in a way.

We decided to push this file to clients upon connecting to ihttps://mygamingedge.online/ servers as of now, others server's admins will follow!

(however it will take effect only after a game client restart)

It will helps new players to avoid fake player count servers hosted by Fastpath & cie,..
and on the other hand it will help total conversion to be more played along side Extra-Life customs maps server!
