I wouldn't exactly worry about dev support being scaled down, seeing as during the earnings call commitment to supporting BFV in full capacity has been confirmed. And while sales were below expectations (by 1M), 7.3M copies sold in the quarter does not exactly qualify as poor sales, especially when you consider the competition BFV had in release period.
On levels themselves, I agree that the cap could use being higher - as it is now, getting to Tides of War level 40 is more of a challenge. But then, once the chapter is over you lose any sight of that result aside from unlocks, which is not ideal.
