An arguement that I truly understand. That is why I said that part of this was a misunderstanding of the tone in the game. I am a Magic Judge. In Magic, we have three levels of rules enforcement based upon the level of the event. At every event that is not at the "regular" level (which covers nearly all store-level tournaments), it is announced that the event is being held at X level and to act accordingly.
Having re-read the tournament rules I see that store champs are held at competitive, but don't recall any specific guidelines as to what that means other than a nebulous "stricter than casual". I am not sure that most of the players even knew we were playing at that level. To players like myself that have played other games, it truly felt like a lower level event. Perhaps something like that might help avoid such issues in the future. It will lead to a colder environment for such events as the expected precision increases but at there will be no further confusion about expectations.
