In my opinion, and given the fact that there is another European leg coming (as far as I know), they should have limited their shows to festivals only.
I do not see any good point with this "not too short not too long format" with supporting acts, and I believe this will affect the attendance.
Personally, I have booked back in Feb or March for the Athens show in the 2nd of July and at that time the tour was announced as SFAM anniversary tour (evening with format). My booking included flight tickets and hotels. Surely, I was not expecting the playing of SFAM in festivals but the way the tour was announced on DT website (dates of the shows listed under a title in Bold "SFAM anniversary tour"), give a strong impression that the shows that will be played in cities that are not part of festivals, such as Russia and Athens, are part of the SFAM tour or at least has the "evening with" format.
If I knew that this would be the case, I would not have booked and would have waited for the 2nd leg.
Anyway, that is the "somehow sad" story of my 600 EUR investment in DT and hope that in the future tours' announcements are more transparent.
PS. The addition of AAL might ease my pain a little; I have started to listen to their material and they are good.
