Think of it this way:
Them doing an acoustic set every single night for most of the last year was pretty special. Now, had they done that five years ago, they might have saved it for that one big show, but the band did it one better by featuring that little set at every show, which, in the words of Scotty, was "especially special"
, especially when you consider they had never done that before in the midst of their normal shows (in other words, not a show dedicated to just that, aka Rotterdam). It's just that this time around, fans got it at every show, instead of just the fans at one show. More fans getting something really cool and rare is always a good thing.
Plus, when you look at the set lists of the past year, unless you aren't crazy about ADTOE, I am not sure how anyone can have a beef. The set were well-rounded and featured a nice mixture of new songs, classics, rockers and the acoustic set.
