Don't complain about the changes if you haven't even tried them
THERE IS A LOT, of changes, and A LOT of fine tuning is going to need to take place over the course of the next 3 months of pre-season. At least give the changes a shot. So many things have changed, old problems may be fixed, and new problems may arise. But thats what Pre-Season is for, thats what it's always been for.
