I did a half with 10 QBA....and...maybe they don't...OK fair enough.
However, it is completely irrelevant. QBA is the absolute last slider I would touch....it de-balances every facet of the game and one adjustment yields another and another and another. In that test, I got a whopping one offline throw out of it...the cost was crappy coverage, anemic run game, poor blocking...that cost is too high...
Maybe you think I am being obtuse about leaving gameplay sliders at default. You might be right, but I still believe that the gameplay is best overall when the gameplay sliders are left at default. Disagree...you can use someone else's sliders, I won't be offended
Sorry, but just not going down that rabbit hole unless I am forced to.
