I really can't comment on this completely as I like to address it in response to the "proper form." As the pros and cons are not clearly listed, it's hard to tell.
On the general idea of "condensing" anything if you do that you get fewer "eyeball hours" simply because if it takes a shorter amount of time to do. And while more people may do they aren't here as long so too much condensing may end up with fewer eyeball hours over all. I suspect such condensations are only considered if the amount of time needed to do the thing is so great players do them a lot less. For instance, even if you "autofought" the tournament before the changes, it still took a long time. Now it takes a reasonable amount of time (to me) and probably, overall, keeps people playing longer. It's a balance between tedium and progress. Too much tedium and progress slows and grinds to a halt, cities abandoned and players move on. Progress going too quickly moves too many players to the end of the game too quickly where they sit, waiting, for something, anything, that might be a challenge to them. Too long a wait and they move on to another game somewhere.
Since, in my sense is that the Spire doesn't take too long and can be done very quickly if desired, I doubt there would be much pro in condensing it....but as I said, I'll wait for the proper list to come out and probably be surprised at the pros and cons. Then I can truly weigh in.
