I noticed the prize drawing dates are not consistent with the dates used for the contest.
"How to Win
4. The winners of the Prize Draw will be selected at random by Turbine (each such person a “Winner”). The random draws to determine the Winners will take place on the days of July 11th, July 18th and August 5th."
July 11th was yesterday, a day before the contest started. And again on July 18th. The only one that will work is the Aug 5th.
"(the “Stress Event”) of Dungeons and Dragons Online™ (the “Game”) occurring between July 12th-15th, July 19th-21st and July 26th-28th 2013 (the “Stress Event Period”)"
A change in the announcement may be in order.
