In a casual event or environment it may be expected that the rules be bent or broken in any number of instances.
As such you can't answer a rules question for that environment as you have no way of knowing what rules they will be actually playing with.
This is exactly the thing I'm trying to push back against.
Under the Casual play rules, including for tournaments, nothing the OP's opponent did broke or even bent any rules. It was all perfectly legal.
Whether we like it or not (and I certainly don't, to be honest) we have two different standards for certain actions. It can be hard to keep that clear and separate, but it's important to do so, and to do so correctly. A lot of the framing here is "It's OK to bend the rules in casual play" which is simply wrong. Taking back a barrel roll isn't necessarily illegal, and going to a tournament doesn't automatically mean competitive rules will be in place.
It can be hard for some of us who always play the competitive rules, even in casual play, to remember that it's perfectly legal to do that sort of thing, and even my response was poorly framed. But I think we need to keep it in mind, and not tell people they're cheating if they're not.
You are correct in the example given in this thread, but the example given in this thread isn't the only way in which rules interpretation/enforcement can be expected to differ in a Casual level event.
The definition of Casual level events is so completely open ended that outside of the TO of a specific event no third party would be able to tell you what the expectations are in regards to rules enforcement/interpretation. Even the proceeding Tiers of Tournament section specifies that Competitive and Premier level events are expected to run to the same standard of play and rules enforcements no matter where they are held, something that Casual level events aren't held to. I'm not quite sure why FFG chose to delineate between Competitive and Premier if the expectation is the both to be run to the same standard, but FFG likes to be confusing.
Still my point being as Casual play is left completely open ended in regards to the level of rules enforcement or interpretation there is no way for anyone but the TO of any specific event to actually answer a rules question in that specific environment because only the TO knows the answer. Casual level events allows the goal posts to be shifted where ever, which is fine, but makes it so the Rules Forum can't really answer whether X,Y or Z is legal or illegal. As Sergovan said the Rules Forum can't help but answer to the Competitive/Premier level, but it isn't because we don't want to be wrong, it's because those are the only levels expected to have a unified universal interpretation and enforcement of the rules/standards.
