Paid map packs do not make them work faster. Just divides up the community which is one of the few things that can actually kill a big IP. If they really wanted to monetize it they would just double down on lootboxes. This isn’t a manpower issue as this is not a big game, they need more talent and/or time. Or all this stuff was lined up before launch for monthly releases to get people to stfu which is more than likely - while they spend time working on maps/gamemodes.
If you’re burnt out take a break and come back in a month or two not a big deal. You’re not meant to be sinking thousands of hours into this.
