i think the problem is, that unwarranted "time wasting" is now just added on at the end of the game, so its kinda pointless, especially the yellow card you get for doing it.
The best type of time wasting now is taking slightly longer for taking goal kicks, free kicks, throw ins etc etc, but defo short of a yellow card, as getting a yellow card for it is just silly imo.
For me, the kind of extreme time wasting we are doing isnt clever, our players are getting yellow cards for it, and the time is then just added on at the end......so its double silly.
