That depends on how you feel about the game itself. I'd say "totally worth it!" whereas the bronze nay sayers would say the opposite.
So it's not really an argument for or against.
It's the same for the delayed off-side calls. I love this new rule for several reasons (don't want to create a wall of text here). But critics have said "what if someone gets injured after the offside? They wouldn't have gotten injured with the old rules". My response is the same: Totally worth the risk, because the new rule makes the game better (IMO, of course). But those who don't like the new rule will say the opposite.
