In current games it's almost impossible to score by shooting straight from defense area.<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>J Angelo Gurzoni Junior <o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>I also like the ball's high speed we have now, but the problem is that those dynamic games are not happening. What most frequently happens is a game with many many indirect kicks. Plays look like snooker games at best, even for the top teams. I think the ball speed may be increased again in the future, but after we can see these dynamical games happening. Right now, there's just too many indirect kicks and game stops. And we can't go back to have bounds on the field, it would be anti-evolutive for the league. Of course, as all the rules, they are not magic answers, teams need to focus development on the topics.<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>J Angelo Gurzoni Junior <o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>Posting here feedback we got: Some people suggested a higher ball speed limitation, perhaps at 8 m/s, or at the minimum 7 m/s.<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>Sepehr Mohaimanian Pour<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>I think 10 m/s limit is great for new field size ! as you know the diameter of new field will be around 9.15 and passing the ball from our corner ( like goal kick ) with the most speed of ball ( 6 m/s ) takes 3-4 seconds to reach the destination ( considering friction ) , another reason that i disagree the 6 m/s limitation is that some teams robots can reach 4 m/s speed and it's not rational that balls maximum kicking speed be 150% of robots speed ...<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>=== About Increasing defense area ===<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>Mani Monajjemi <o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>This is really a good idea.
