Update. I called in and spoke with someone regarding my issue on the phone. She was helpful and informed me that she would open a new ticket to have my entire K70 Lux replaced on RMA. Not just key caps but the entire unit.
New ticket is opened and the next day support requests me to re-submit all of my information for warranty (original invoice etc) along with photos of ALL cracked key caps that need replacing. I told them I would prefer to not have to pull 100+ keys from my keyboard, photograph, document each and submit but they said they need me to.
This is ridiculous. Between emailing back and forth, looking for information online, and calling and sitting on hold I've spent more than enough time that is worth it.
