It's good that they're showing faith in their new album. Even though most people don't rate it, they should believe in it themselves, otherwise it's not worth making albums.
However, as I said, when you've only got 30 minutes, you don't flood the set with new songs. You do that when you've got a headlining slot.
Dante's Inferno, whoever said that, would be a stupid idea. Just as you don't play 20 minutes of new songs in a 30 minute set, you also don't play a single song that's going to take up half your time on stage.
