Should we rate teams or individual players?

Teams, if your rosters are stable and named — that is the usual shape of a GB community and the team is the real competitive unit. Rate players instead when the fours are assembled fresh from a pickup queue each night. Both can run side by side on separate leaderboards.

Can practice scrims be recorded without affecting the ladder?

Yes. Set the queue to an Unranked mode and results are recorded and kept in match history without moving any ratings, so a practice queue and a rated queue can coexist in the same server.

Warzone is a battle royale, so its scoring is placement-based rather than head-to-head and the setup is quite different — placement-and-kill points over a block of drops. The Battle Royale page covers that configuration.

Call of Duty Scrims, GBs and Elo Leaderboards on Discord

GB-shaped 4v4: a Hardpoint-Search-Control rotation in one series, and a ladder for the same twelve people.

Create a Call of Duty league Browse Call of Duty leagues

Competitive Call of Duty is not one game mode, it is three played back to back. A GB is a Hardpoint, then a Search, then a Control, and calling any one of them "the match" misdescribes what happened — teams routinely drop a Hardpoint and take the series, and everybody involved understands the series is the thing that counts.

That has a direct consequence for a ladder, and it is the decision this page exists to get right: the rating should move once per series, on the series result. Rating each map separately triples the movement, credits a mode specialist for a series they lost, and produces a leaderboard that disagrees with what the room saw.

The second thing that separates Call of Duty from most games here is that the competitive unit is genuinely a team. GB communities are built out of named four-man rosters that have existed longer than any individual ladder — so unlike Valorant 10 mans or CS2 pugs, rating the roster rather than the player is frequently the correct answer rather than the exotic one.

What these communities almost always lack is persistence. Results live in a channel, scroll away, and the question "who is actually the best team here" gets settled by whoever argues hardest. That is the gap a ladder fills, and it does not require changing how anyone already plays.

Setting up a Call of Duty leaderboard

The decisions that are specific to Call of Duty. Everything else follows the general setup guide.

1
Rate the roster if the roster is real

Build your teams with /team_admin create, rate them with Team Alias (Specific Format) at 4v4, and queue them with /queue_team. That is the stack for a community made of named fours that scrim each other — the team is the competitive unit, rating it sidesteps the attribution problem entirely, and /team_admin set_captain puts result reporting in one person's hands per roster. Switch to Player (Specific Format) only for an open pickup queue where the fours are drawn fresh each night.
2
The pool is map-and-mode pairs, not maps

Build your map pool with entries that name both halves — Hardpoint — Skidrow, Search — Terminal — because in Call of Duty the mode is at least as much of the competitive decision as the map. Then set Map Voting Strategy to Captains Ban (no reroll) so the veto works the way both captains already expect it to.
3
One rating change per series

Set Match Format to Best Of 3 (or Best Of 5 for a full GB) so the ladder moves once, on the series. This is the single most consequential setting on the queue, and the default — Single Match — is wrong for this game specifically.
4
Practice should not touch the ladder

Set Ranking & Voting Mode to one of the Unranked options on a practice queue and results are still recorded and still show in match history, but do not move ratings. Communities that skip this end up with a ladder that mostly records who was willing to warm up in public.
5
Give the ladder a visible payoff

/tiers grants Discord roles by rating band, which is what turns a leaderboard into something people see without visiting a page. Pair it with a season rollover on whatever cadence your community's attention actually has — for a scrim scene that is usually six to eight weeks, not a year. If your server also runs Warzone, that is a placement format rather than a head-to-head one — see the battle royale setup guide.

Call of Duty GBs: Rating a Series That Isn't the Same Game Three Times

A GB is a Hardpoint, a Search and a Control — three different games with one result. Here's why rating each map is worse in Call of Duty than in any other shooter, whether to split ratings by mode, and why the roster is usually the thing to rate.
