That is disappointing. That is why I really miss the sliders that used to exist back in M13 I think where you could determine the percentage of carries RB1 and RB2 were going to get.
Is there any way to fix this issue by adjusting sliders? Lower fatigue? I'm fine with re-adjusting sliders for the games I play against the CPU. But the rest of the simmed stuff would be great if it were more accurate.
