I dunno; Joe Elliott (who I believe runs that band, so to speak) is somewhat realistic (read: cynical/jaded) about the music business. He's basically seen most of his bands material summarily ignored over the past 15 years, so that setlist is almost EXCACTLY what I would expect from them.
I don't think he can credibly sing most of HnD now, anyway, and let's face it, the setlist wasn't that different when I saw them in 2014 (the only difference were the three new ones and Rock On added and Two Steps Behind dropped), and the fans reacted to those songs. Armageddon it, the place went NUTS. "Bringin'..." started acoustic and ended electric (and had Switch 625) and from that point on, it was a hitfest and the crowd reflected that.
May not be my favorite, but as a general proposition, the band gave the people what they wanted.
