I know it's boring complaining about the cost, but I was just looking back at the prices of previous DT shows I've been to.
Prog Nation - Glasgow - 2009 - £33.90
ADTOE tour - Glasgow - 2012 - £36.40
DT12 tour - Manchester - 2014 - £42.50
Astonishing tour - London - 2016 - £64.95 (Ticketmaster)
I&W and Beyond tour - Glasgow - 2017 - £59 (A second ticket for my friend from Ticketmaster was £64.83)
Those were all pretty good seats as well, except Manchester (and Prog Nation which wasn't seated). One was 2nd row and three were row H. Manchester was row X, but still in the stalls.
At least there are cheaper seats further back, but it's crazy that to get a decent seat for Glasgow this time, you have to spend more than DOUBLE what you did for a similar seat at the same venue in 2012.
