But is it keeping up on the player numbers or is it in decline
If the latter then fizzed needs to do some marketing because it does not imho deserve to fall down the ranks
Warzone's player numbers have historically been remarkably stable, per Semicedevine's leak last summer (https://bit.ly/warzone-datadump
I doubt that's changing now.
One way you can easily
check is to create a new account and see what player number it gets (ignore the first and last 2 digits of the profile ID; the middle ones just increment by 1 for each new account). I just created one and it got the player number 1336359. Subtracting the player ID of an account I created in very early November of last year, we see that the player number has increased by ~25,500 in the last 67 days: about 380 new accounts per day, in line with Semice's old calculation of ~280/day.
That's entirely consistent with Warzone's growth rate before, so it looks like Warzone growth is holding steady (or even increasing) in terms of new accounts (that get IDs) created each day. There may be other trends going on with how many accounts stick around, how many old players retire, etc., for which Quicksilver's analysis above is more useful. Fizzer's own statements on stream (to the tune of "no one really leaves Warzone") make me suspect Warzone's retention trends are rock-solid for its niche genre.
