I have never once used quick counts since it takes away my favorite part of hitting, namely approaching each at-bat as something like a game of chess with research, patience and a bit of guesswork necessary if you want to get the better of your opponent. Cut straight to the chase and what should be a rather cerebral game turns into one of reaction. I realize some will prefer that but it's simply not for me.
But the new features that allow more gameplay options during simulation seem like a different animal to me. It's kind of a way to selectively dip your feet in the water rather than jumping all the way in or staying completely out every game. I'll continue to grind through every single gameplay moment during my RTTS's but these new jump in/jump out options seem ideal for allowing players to determine their perfect pacing in franchise mode.
