This is another thing that has continually been happening, and is a big issue for multiplayer. Sony was able to get over two hundred players playing together in its game MAG. It was also so dry and visually bland a game that it could have been a PlayStation 2 title in pre-Alpha.
Some developers have caught on to the idea that more content is better than grander scale, but still are struggling with it. Titanfall offered over twenty maps at launch, and released a bunch of free content updates, but also tried to charge ten dollars for three packs of three new maps. This was a terrible idea, and the game benefitted greatly by just letting everyone have the new maps for free.
This shouldn't even be news to developers. For years older games like No One Lives Forever and Unreal Tournament offered free map packs and new game modes as updates, not something you had to pay the right to use. Splintering communities with pay walls is one of the worst things you could do in multiplayer.
If developers want to charge for something, then they should actually take a note from Batman: Arkham Origins and charge for new gear, or better yet, Battlefield 4's shortcuts. I know what you're thinking "but that stuff is the worst!" except, it really isn't. Think about it.
Consider a world where all content updates are free, so you continually have more and more game to play. Except, since publishers will still want to make something off of the game, they offer new players the ability to catch up in the progression system. They'll still be new to the game and unsure of what gear to use, meaning balance is maintained. All the meanwhile, you've got a consistent stream of new modes and maps to play on.
As compromises go, this one pays off way more for the core player base than the current model. It'd be awesome if we could just get the content for free, but not all publishers and developers will go for that approach. Still, anything that takes us out of the age of Sanctum and Call of Duty-style paid for DLC is a welcome move towards benefiting the player base.
