Is that still happening? It was struggling for players a few years back.
Yep. They are plagued by an underlying purpose to the game being larger-scale territory control/capturing bases and moving forward, but the developers at the same time making the game attractive to those who are accustomed to playing Battlefield/CoD etc that just focus on having the most kills at the end of the 30 minute round. Which means, for example, that they do things to make it tougher to destroy enemy mobile spawn points, so that there can be "stable fights" that last a while. While that sounds good for people who want 30 minutes of kills, it makes it tougher on players trying to defend a base and has overarching effects on the territory control game. Don't get me wrong; a lot of the stuff they do to make it more like Battlefield is good. Some of it does detract from territory control though.
Honestly, if this is how a game that starts out planning it for larger-scale territory control, compromises to make it attractive to round-based kill/death ratio focus players of other games, I'd like to see how a round-based game developer would do a territory control game. Unfortunately, last I heard, DICE said they had no interest in MMOFPS, that was 3-4 years ago, who knows if it will remain that way. And I can't think of any reason CoD's dev teams would care for this.
No idea if they are overall struggling for players though; the server I play on has plenty.
