Hasn't the homogenisation on the outdoor courts (which is the biggest part of the season) changed the metagame for less net play in general?
Do you think the game play would be different now if they switched back to carpet on the indoor season?
(Honest questions, as I barely followed the tour back then.)
I think it would encourage attacking tennis. But in the course of a year there would be little change in the game play. At the very least it would force players to adapt and diversify the calendar, providing a oppounity for attacking players to gain points.
