The way baseliners get winners in realistic mode by using the advantage of extra stamina that they have is the major drawback in the mode. If players with other styles cannot win points especially while playing rallies, I think people lose interest in the online tour which may follow realistic mode in 2014 For Example, if i hit a decent return to a power baseliner, he just attacks all the time with power strokes and on the other hand even if i defend well.....i tire quickly than baseliner and also if i hit power strokes it will be even more tiring. Coming to net becomes so tough because i don't have any power left to push my opponent into defensive position with my shots and thereby killing Volleyer/Varied styles. I think all styles should be given equal stamina. However to help baseliners, they should be given the advantage of hitting the shots "consistently" deeper(not have more stamina) compared to other styles. But in fair mode as the power effect is reduced, i feel it justified all styles. However i agree with people who said that Fair mode is slower with ground-stroke speeds ranging just a max. of 130kmph. So please give equal stamina to all styles to justify all styles and then keep realistic mode for online tour.
P.S. John Isner and Nicholas Mahut were volleying most of the time in Wimbledon epic match and they have exceptional stamina too. Varied style players have same stamina. Stamina should not be dependent on playing styles.
