That's odd, this is certainly not the case. As I said, I thought it was 14, turns out, I was wrong as well, it's 12. I pulled this from the 2011 site via Archive.org:
Attendee Age Restriction
Some content at BlizzCon may not be suitable for children. Anyone 12 years of age or under must be accompanied by an adult. Absolutely no children 5 years of age or under will be permitted to enter. No strollers will be allowed in the Anaheim Convention Center.
-- So to the OP, yes, you can go without a chaperon.
