I think thats a pretty damn good setlist! Yeah ok it could have been longer, and there are some classics missing as you mentioned such as Shoots and ladders, Got the life and A.D.I.D.A.S. But you have to appreciate that they are touring their new album, so 4 new songs isn't exactly outrageous.
Plus you got to hear fake, trash, faget and dead bodies everywhere - not songs that you would hear every time you see KoRn, and I think it's great that they do this each tour. (For example greatest hits tour - Dirty, 4 U. And their last tour, we got Good God and Divine). It's songs like this that I'd happily hear rather than Here to stay, twisted transistor, coming undone etc.
Also, I'd hardly call Twist, Divine, Politics and Hypocrites 'classic KoRn songs'.
On and on South of Heaven...
