Yeah...I see what you mean...I guess the confusion comes from the preview itself and it's inference regarding Quick Strike. I have the gut feeling it'll play out the way I have described (it preserves the spirit of the ability and would explain what they meant in the preview), but so far nothing in the rules indicates it will go down that way.
There probably will be a clarification in the rules sheet of the expansion...something along the lines of : ''actions cannot be taken before choosing a defender'' or something like that. Otherwise, the preview is simply misleading.
I realize I was jumping the gun, but I was simply trying to wrap my head around this conundrum...Besides, sadly, the ruling about Shadow Cards shows that the letter of the rulebook is not always reliable, or at least a reflection of what the game designers meant.
Still, you are right, might as well wait and see...
