Back in 2006, comics were the only media I could access to follow the story, since they were available for free on BIONICLE.com. As a result, I only discovered YEARS LATER that the Nuva were actually sent to Voya Nui first, fought the Piraka and failed, and that Jaller and company went after them through Karzahni.
I understand having to cut content due to budget or size issues, since a comic couldn't possibly fit entire books in it. But it's such an IMPORTANT plot point, you would think they would at least mention it somewhere.
