Can't help feeling we'd have been better served with 2 books of HH rather than Mean Arena. Looking at Barney the page counts are about the same (HH+Inferno is 295 to Mean's 288) so I'm not sure why they decided to go this way.
Yep, two volumes that were an easy miss for me. Even Slaughterbowl can't convince me to get them! Mean Arena already lives in infamy as the strip that killed the Extreme Edition.
