Ofc you can say that…
Imho it is not only the daily boosters, it is also a matter of mission score and SL/RP earnings which were nerfed like hell - but most of them came in small and tiny steps. Even if you play just for fun the income nerfs summed up over the years.
Example of score and income some years ago
I remember those times in Air RB when u got 300 points (score) for killing a single ai tank - on maps like Sicily you could kill 12-14 of them in under 4 minutes with 2 SC 1800 drops - and kill 50% of the enemy tickets with that.
Combine this with an antimech order and a booster you could earn >280k SLs if you were good enough to time and aim the drops perfectly and to choose the “right” flight path in order to shake off ass sniffing A2D-1s and F8Fs…
But - those maps were “updated” and aligned with all the others, they nerfed the destruction radius of the SC 1800, nerfed speed / rip speed to even get there, etc…
