I think I'll be okay with the slow start. The premise is about refugees surviving on a new world, so it would a bit ridiculous if huge dramatic action is popping off at the start.
The lesser focus on an over-arching narrative is a bit sad since I really like Xenoblade Chronicles's story wholly and not ironically. However, I've seen more assessments of indifference or apathy to Xenoblade Chronicles's story than I have of appreciation online. Not trying to excuse Xenoblade Chronicles X's decisions, but it makes sense with the premise for the lesser focus on a main story and more focus on a myriad of side tales.
