As for myself, some of the old songs I'd like to be changed up (like Antisocial... but I know it wouldn't happen) and I expected that a fair amount of new material, but what really pisses me off is the short set. I don't think people would complain so much about the same old songs if they were actually playing a standard headlining set. If they pulled out a 16 or 17 song set with all the current songs plus another one or two off Spreading the Disease, something nice from Persistence of Time, and maybe another from Among the Living I think everybody would be satisfied for the most part.
