Comparing Dauntless to R7-T1 looks more difficult than comparing Dauntless to Push the Limit because one is a trigger and the other is an action. It's easier to see that Dauntless and Push the Limit are both triggers and are templated similarly.
One being a trigger and one being an action has nothing at all to do with how you read the effect of the ability. You keep claiming that, yet have provided absolutely nothing to support that it makes any difference. Can you provide even a single example where the same wording has a different effect if it's an action vs. a triggered effect?
Yes, Dauntless is closer to PtL... but the whole point is that the R7-T1 ruling, if taken as precedent, would have implications for Push the Limit as well. Which is why a number of people were surprised by the ruling, and why I said above that it shouldn't be taken as precedent.
But they really are the same text for effect. If you'd like to actually try and support your assertions, rather than simply claiming them again, I'd be all for discussing where you got the idea that the origin matters. Because, again, you have said repeatedly that it does, yet haven't even bothered to support that assertion. If it matters there should be some rule that says it does, or some ruling that demonstrates that it does. But what we have is exactly the opposite. You don't acquire a target lock any differently from the action than you do from Dutch. If you get a free action, it's not handled any differently if it comes from Lando (trigger) or Squad Leader (Action).
You keep claiming these distinctions as something that matters, but there is ample evidence that they don't, and you've provided none that they do.
