Personally I think they should get rid of the PMA and My December piano versions. They could put in more HT songs like Runaway or By Myself or even Meteora stuff instead! In Between, HHH and TLTGYA are fine to me because I like the mixture of heavy and soft songs they have in their setlist and these three songs deserve to be played!
Last but not least, I won't miss BTH and SOTD too
