I seems for a couple of months now, the bots are on a significantly lower difficulty.
We find ourselves easily completing maps, which I remember were much harder, even with more people.
Spawning seems to be much lower in flags that are being currently taken.
It used to be the case that Sbeneh Std or Khamisiyah, it would be very difficult to take South city or Chemical, because of bots constantly spawning.
Charlie on Sbeneh used to be impossible.
Now I managed to complete these maps with 20 people. It doesn't even seem like bots spawn in the base, because sometimes the tank column never comes.
Muttrah Lrg used to be very difficult with less than 20 people, because enemy would Blitzkrieg all the way to North City. Now we can finish Muttrah with 10 people, because we cap West City before enemies even get there.
Jets used to drop bombs, now they only use cannon and sometimes rockets.
TOWs and AA mounts would shoot very quickly and accurately.
Bots still seem quite accurate with small arms fire, especially in forest maps, and RPG are still quite prevalent.
While this is fine for late nights and mornings with low population, we now really struggle to find any challenging maps. Unless we play Vietnam 24/7. Even that isn't guaranteed. I remember playing Barracuda ALT for 3 hours 1 round to get through Swamp and Supplies. Now I can't remember last time it took us more than 1 hour to complete this layer.
