Having one style that dominates makes it boring. In the early 90s I didn't like the 3-stroke rally points and wished for more rally points and longer games.
It wasn't that bad at all
Without nuances it looked like this:
"All-serve guys": Ivanisevic, Krajicek, Rosset
Serve and volleyers: Edberg, Becker, Stich, Sampras, Forget, T.Martin, J.McEnroe
Offensive baseliners: Courier, Novacek, Korda, Agassi, W.Ferreira, Lendl
Grinders: Chang, Bruguera, Gustafsson, C.Costa, Muster, Chesnokov, Krickstein
IMO it was quite balanced and entertaining.
