People keep keep using the HLC as a gateway to rolls being different than rerolls, but HLC specifies "immediately."

The "immediately" argument again...
It has been shown over and over and over again that the word "immediately" holds no meaning in X-Wing. There are a ton of examples of cards that have the exact same trigger but one has "immediately" and the other doesn't - yet the player still gets to resolve them in the order of his choice.
