You can only suggest getting rid of the offside rule if you actually are not a fan/player. It's a totally ridiculous suggestion - sorry.
There are def issues I'd like to get sorted. Like time wasting, cheating, professional freekicks (I'd like these yellowcard to give a 10 min suspension as they are so effective to kill the game). Having said all that I've thought the refereeing has been very good so far.
One thing to keep in mind is that it's impossible for the referees to get it all right. Because they are human of course, but also because everybody never really agrees even after the fact with all camera angles if it indeed was a freekick, penalty or a yellow or red card. It's a continuous discussion after every match it seems.
