I would like to see an option to berate opponents and the ref during the cut scenes after a foul. Maybe press X to complain or Y to taunt eg. There could also be an option to hold R2 for more subtle abuse! Or to take it further- hold L2 and right analogue for 'manual' chuntering ie point the arrow to who you want to confront.
If you use this tactic right, the ref gives you more decisions, too much you get booked or sent off. There could even be a gobshite skill card for people like Van Bommel and 'JT' etc
It would be great.
