After watching yesterday's game LCW vs Viktor Axelsen Dubai Super Series Finals 2016, I'm wondering yet again if it'd be wise to allow challenges to be used against umpire calls, net touches, service faults or whatever. At 19-18 in the final game, umpire made an unfair call for net touch while replay wronged him and commentators agreed that the call was wrong. Umpires are humans and they can commit mistakes but there should be nothing wrong in challenging them to keep the game Fair and athletes satisfied. High speed cameras can solve all mysteries. At the end we want fair results, right? I'd hate to watch unfair service fault on flick serve at match point. And badminton is a game where we can achieve 3rd umpire results without wasting much time. If you think one wrong umpire decision doesn't affect the game, you are wrong. Sports is often more psychological than physical specially at the end when you are out of energy.
