Nonsense. In a multiplayer game, it is not about having the freedom to take however long you wish. There is an opponent and his/her time to consider. If you desire that kind of freedom, play a single player game. You can take as long as you wish.
Besides, the 90 second timer was set up arbitrarily by WGT in the very beginning, and since then people have begun to use it as a crutch to chat and such. It was not based on any real-time experience, it was simply a number chosen. If the arbitrary time chosen had been 60 seconds as opposed to 90 seconds, people would have adjusted their game accordingly. Experience through over a year of multiplayer game play has shown that the 90 second timer(plus a few timeouts) is too long a default time for matches. Most of us have been at odds with the default time since the beginning. No one ever complains about people playing too quickly, only that they are too slow. That alone speaks towards lowering the default timer amount.
Try visualizing your shot before it's even your turn to shoot. That way you'll be well prepared with club selection, spin, and power and all you'll have to do is adjust the aim accordingly and go. I hit most every shot within 10 seconds, putts included. Even with a practice swing or two, there's no reason a shot should take more than 30 seconds, outside a difficult putt here and there. Therefore, lowering the shot clock to 60 seconds would give ample time to both set up the shot, give a practice swing, execute the shot, and have about 30 seconds to include a chat comment.
Consider also that an extra 30 seconds per shot multiplied times an average of 36 shots per 9 hole round equals an extra 18 minutes of real time game play. That is a considerable figure, and I believe the arbitrary figure needs to be adjusted downward. Even a 75 second timer over the course of an 18 hole round would reduce the real-time amount of a match considerably. This is definitely a must for the future to keep the game viable and moving along in a timely fashion.
