The issue with firestorm was a bit the same as blackout. Released after a while when player numbers are lacking. Need huge numbers and only way to do it well long term is FTP. Pubg was the exception for a while but now it's hard to even get an AU server. Yes it's cashing in on a trend but it's clearly what people want. Smart business really. So long as the actual battlefield 6 game modes aren't neglected. Modern warfare is doing just fine with warzone off to the side. They are cleverly linked with season pass and ability to grind on modern warfare for warzone classes.
