From Reddit: http://www.reddit.com/r/Guildwars2/comments/267lr8/festival_tokens_as_a_currency/
One of the best update Anet has ever done was the account wallet, why not put Festival Tokens as a currency and avoid the annoying character swap that we used to have to know how much of a value I have.
This could apply to any other token we’ll get in future LS updates.
