I don’t believe that DLS will ever be replaced unless the big 3 collectively put in a request, but since they haven’t made any such requests I feel that it’ll continue as it is. Lastly I feel that DLS adds an sense of excitement especially for me, because I know that teams will now have to go out of their way to win and I understand at times it may not be what fans want, but I yet feel it should be retained despite all the negativity surrounding it.
I agree here with you because it's most balance's system which is working in cricket for long time, and we have no big concern about this from any country, specially after incident which declare England as winner in 1992 Cricket World Cup where South Africa were favorite to win, and they lost their golden chance for winning World Cup.
On other side if they want to end this DLS system we have only one other option which is not going to implement because it needs too much money which is not possible for most of the cricket boards, it's we can play under roof which is only other suitable option but still we can go with this DLS as it's good and fair for all and most of the cricket world is happy with this.
