I've been pretty lucky in my 3 years of seeing the band to get to see some cool songs now that I think about it. Tripping Billies > Halloween, YNK, Grace, full band WAYG, 2nd instrumental KKJ ever, Ditch, multiple BOWAs, 2 LLDs, multiple Grey Streets (my favorite song).
I just happened to look at some of the adjacent sets to mine and giggled though. I only caught one show in 2012 and 2013 before starting to really get into it last summer.
In 2012, I missed So Right and stop-time WH by one night (always wanted to do the woo's). Not that upsetting.
2013 was just a tad bogus, although I don't wanna complain about KKJ, LLD and Ditch. VA Beach was bookended by Charlotte and Bristow, both of which got Crazy Easy and LBV. Charlotte also had full band Recently (getting Recently acoustic was cool, but that song about Carter for me) and Two Step > Ants > Halloween set closer. I missed Spoon in Bristow too. Both of those shows also had liberations (KKJ = cool, ODH = not as much).
2014, again not as bad. Only qualms are Pig and IOY (really wanna see this one live) the night before Charlotte, but it was WPB N2 so I can't really moan too much.
I'd say the pros outweigh the cons
