The push for consistency has created more problems than it fixed, because they have tried to remove any subjectivity from the decision making process. The rules were loosely written because it's a game, and one where things move fast and unpredictably.
Every decision should be weighted with whether or not it had an impact on play, not whether the other umpire paid something to the other team at some earlier point in the game, or in 5 weeks earlier in a different match.
If umpires see that a team, let's call them Hawthorn, are doing something that appears to be a tactic rather than a couple of misguided players, they should have the autonomy to react to that, not be bound by an edict to be consistent.
