Blizzcon tickets: Going postal from a frustrating experience

Ok so it happened again this year. Within minutes of being available, tickets for Blizzcon were sold out. Tickets were limited to 5 per person and anyone with a brain will see that there are hundreds of tickets being sold on Ebay. It's sad that people who really want to go and not scalp are getting frustrated and sad.

One suggestion for the next day of sales (May 30) would be to limit ticket purchase to those who have not purchased tickets today. For blizzard, a sale is a sale though :/
