Iron Maiden, Slipknot, Gojira and now Scorpions are ruled out due to playing elsewhere in France. Don't know what Hellfest got in their pockets, since the headliner pool for next year doesn't look very large by now.
I'm in fear of becoming the devil here but the previous system was a little bit of the have's versus the have not's with regard to the knowledge of how to play the system. As someone who didn't know how to play the system i tried for about 5 years without any luck. I only ended up getting to Glastonbury for the first time due to a friend getting tickets as a supplier. Gives those people who've always wanted to goa fair shot. Good luck to everyone.
