I don't watch any other A League games other than the Nix and I think I'm pretty unbiased when it comes to evaluating this kind of thing but the standard of refereeing of the Nix games is usually very poor. When the refs have a bad game, they tend to have howlers and [without being too precious] usually it goes against us. If this is the usual standard of officiating in the A League, then they have a serious problem. The League will not grow and get better if the officiating doesn't keep up.
Edit: Just to add, officiating is an issue in most sports to some degree or another, but when continual poor officiating has an effect on the outcome of games [not just 1 or 2 and every now and then] it is fudgeing serious issue that must be addressed by the powers that be.
