I play with sliders based on Josh's set and philosophy, with only some minor tweaks not really worth mentioning, except one:
I have injury slider set at 45 inside CFM (50 in MM) and I barely see any injuries except fo my HBs, and even these are no longer than out-for-the-game. No off-ball injuries to anybody, though. No injuries to other positions, game-long or out several for several weeks. But I am still afraid of what I would see with injuries turned up to 50, especially regarding HBs. I really do not want my HB room turning into a MASH unit, which obviously is your case, and many others see that, too.
Josh what do YOU see, especially in regard to your HBs, but also in general?
