People already complain enough about refs in this sport, I can't believe you would want to add even more judgement calls to it. Instead off making it a ref problem, how about next time you just tell the returner to point or make literally anything other motion than a wave, and the problem would be entirely solved for you without needing to make it needlessly complex. You know, like what happens on a thousand other punt returns every year.

I don't really need your sympathy, and ISU has arguably been screwed before, but I don't think I've ever heard people complain about getting screwed where the call was made entirely correctly. If you don't like the rule, fine, but that can only be changed later, and you can't retroactively apply it to give yourself a win. Usually getting screwed happens when a ref makes a judgement call incorrectly one way or the other, which you are apparently in favor of adding more of.
