I get your point. And in my point of view it's right on the money. Surface homogenization has played a great part in today's tennis, and that, on my point of view and personal preference, has just made GSs "predictable". Sure people would want to have Federer, Nadal, Djokovic and Murray in SF as opposed to watch a Federer vs. Gonzales (AO Final). But that's the beauty of the sport, having upsets on any given day, having great matches from people you don't expect. I mean, I, as a tennis fan, would rather have an "unpredictable" GS than what we have today. For example, if Agassi would be playing today, he would have "probably" accomplished more in Wimbledon, or some other events. I am not a GREAT fan of S&V, I would rather have some long and some short rallies. You talk about the top dogs having an all around game. I differ from this opinion. For example, Rafa is a warrior on court, his speed, his movement and his reaction time are amazing, but he is lacking on volleys. Murray has an all around game, or even Djokovic, but they don't come to the net very often. Let's recap here, when in the 90s, on Wimbledon, 80% of the points were won (or lost) on the net. Now, it's all about the baseline... There are PLENTY of players who know just the "basics" about volleying and they are getting to Wimbledon QFs or even SFs, and that wouldn't have happened in the 90s not even with today's players. Players today are really looking into fitness and forgetting about learning new tricks or new skills, why would they? They don't need them. And that is why I don't like surface homogenization, they are taking some skills out of tennis.
I think I should just accept it and move on, after all tennis is a business and it is just OBVIOUS than with today's tennis, business is blooming and getting their desired SFs at GS. That's all there is, if you would say that they are doing it for the players I would still complain but would understand somewhat, but it's all about the business and having TV Ratings, selling out tickets for the MUCH EXPECTED SFs at GSs and whatnot, it doesn't have to do with quality tennis anymore.
In the end, I just don't get it and I don't like it. I would rather have players like the 90s, where Bruguera can go to win RG but would have no chance at Wimbledon, or like Edberg with his beautiful volleys that wouldn't stand much of a chance at RG than Nadal, Murray, Fed and Nole taking everything home, this is getting harder for new comers, now background accounts for nothing and the surface where you "grew" up is just another regular information.. That's what I am saying.
