First of all in a casual game who cares. Especially when playing with a player for the first time I tend to allow new players to take back actions or perform actions retroactive as long as I haven't moved any ships or just let them take the focus or evade.Now for tournaments I can understand the need for more precise order and don't allow for things that would be allowed in a casual game. However in this case I would call the official who would more likely side on the word "may" saying Dash doesn't have to land on the Asteroid even if his ability allowed him to and then the TO will tell you to continue to play the game as you only have so many minutes before you have to go to the next round.
Pre-measuring is not illegal as this is not 4th or 5th edition 40K and it has been clarified in official matches when it is allowed. Using the template to see if the action can be done is the procedure. Not using an ability that has the word "may" is listed in the rule book if you read it. The above in not cheating, also what advantage did Dash gain other than to avoid not being able to attack because of obstacles? That's what Dash was designed to do is use obstacles to his advantage. That's what the extra point cost is for. Cheating would be something like Barrel Roll Creep but that's another topic.
No one is confused here unless this is another one of your jokes then you are confusing everyone dear Confused Confuser.
Either way point here is casual games are for fun. Official games are on a time schedule. Arguing over rules is counterproductive to both. Call the TO who will take the word "may" heavily on his/her judgment and then play on it whatever the call was.
Who cares? People who want to be competitive even in casual games, that's who. I play with my friends a lot outside of official events, but that doesn't mean we don't prefer the rules to be both balanced and consistent. The core rulebook doesn't always provide that on its own. See my next point.
You still go back and start with the rule book. The FAQ and errata only provides clarification and minor changes. Now any change in errata takes precedence but it is not a substitute for not using the rule book. Also I did mention it would be nice to have an updated rule book however that will be at a later time when they release a new starter set.
If you start with the rulebook, the imperial player will get initiative every time. The FAQ doesn't simply add to the existing rules, it changes them in some very fundamental ways. That having been said, using templates to measure range at any time outside of an appropriate window is most definitely cheating. See page 9 of the FAQ.
You, and perhaps some other people as well, seem to think that the word 'confusion' implies that nobody can understand how to resolve the scenario. We each have our own way of interpreting it, the confusion comes into play when not everybody can agree. That's what's confusing.
