Fair enough. As of now, games would be too long. On a average game, 'effective play' is around 60 minutes.
Thus, two halves of 30 min have been discussed. Disagree that the only change would be more time awareness (which is not perceived as an issue) and that everything would remain the same. I think how teams manage time, gameplays and tactics could be affected (maybe for good!). I guess fans and authorities don't feel the system is broken therefore why fix it. Someone posted FIFA is reluctant to innovate and that is generally true. I will think about pros/cons.
