If you read post 1, Josh provides great detail on his philosophy. Sliders impact one another and you have to use caution in adjusting just one click of one slider.
From Post 442 from Josh:
Frankly speaking, 50 CFM INJ is not satisfactory from a gameplay perspective this patch. Remember, the CFM INJ slider is essentially a 'recklessness' slider - the higher they go, the more players throw their bodies around (which amps up the collisions and the 'closeness'). With CFM INJ at 50, there's very little interior pocket movement, the tackling does not have any sense of 'organic' feel (it is incredibly 'hit stick-y'), and overall it just feels very 'hyper'. I don't believe the patch "broke" anything, but I think we sorta accepted it pre-1.10 because it was necessary for coverage purposes.
