Yeah in my first game with the patch I did't even see ANY subs on the DL or in the LB corps, whereas I was seeing them before.
I just went ahead and jacked the fatigue slider up to 75 for a game and actually saw some really good sub rates in the front 7. No one disappeared either (maybe that's fixed??).
Of course this is offset by the fact the OL and DBs are subbing too frequently, but I think I can live with that if it means a solid rotation in the front 7 and no one disappears.
Oddly enough didn't see much HB subbing even with fatigue at 75. Go figure.
Has anyone consider global fatigue rating edits as a workaround? Mainly boosting OL so they don't come out. Less drastic edits could tweak the sub rates for other positions.
