It certainly is! Then again, with the increased length of the rallies it requires more stamina and higher consistency to pull off one loop after another. it might not matter nearly at all to the top level of competition, but what about the average amateurs/enthusiasts that did not go through the proper training process?
How many of you have been bullied by that old man in your club with a weird rubber setup of pimples/anti spin that simply kills you with his serves and service returns? I am guessing most of you because there are always at least one of them around (coincidence? I THINK NOT!). So whats gonna happen to that guy when his spin advantage is nerfed/gone? Is he still going to enjoy the sports with all the frustration he will be going through? I dont think so.
Ok lets take a less extreme example then. Say....a final year uni student who is in the varsity team that has been playing for several years. He has got the stamina, but his game relies on that one opening shot that will force his opponents into a mistake for him to get the point in the next shot. Now with the new ball, it slows the shot down to a returnable level for the opponent, and suddenly the student's go-to tactics he's been using for years is suddenly gone, and he wont have any more time to adjust to it as this is his last year he will be playing in a proper training system. Will he still enjoy the sport then? I dont know. At the moment, this case is very common.
My personal opinion on the matter? I am having little to no problem adjusting to it. Yes I have to strike the ball a bit later during serves to prevent it from flying too high, and yes I have to recover quicker in response to the higher number of top spin to top spin rallies now. It has, in my opinion, made the game more challenging and refreshing and I am enjoying it. But this is coming from a player that was in proper training regimes ever since he started playing.
So.....Yes it has definitely made competitions at the top level more spectacular, and also made games at a somewhat higher level more interesting than they were. However, I dont think this change is that good for the sport as a whole. And the steep price tag of the new balls doesnt help the cause in the enthusiast scene either.
