Disabled by default.
What I meant was, what is the nature of the mentioned "asymmetry" in the rebuilding process?
update While waiting for an answer, I think I figured it out myself – it's like a mirror, but the guild will rebuild differently in symmetrical cities for different opponents. BUT how does this imply that it's better to disable it than to enable it? The logic is interesting. What are the advantages of this decision, and what disadvantages were considered?
And another question – why set a timer of 16+8+1 with a turn time of 117 seconds for a tournament that is supposed to be the "most prestigious"?
h3dm1 is a very skilled and complex map from the very beginning to the very end, and both the early and late game are very intense, and this isn't even an average timer – it's a fast timer.
lucky has been playing a lot of mirror matches recently (and I've been watching his streams), and the way he manages things in the late game is impressive, so why risk it? You could add 15 seconds to the battle time and 30 seconds to the turn time, and add a few more minutes to the starting time; I think 20 to 25 minutes would be a good starting value.
Compared to SoD, 7 days of simultaneous turns still noticeably save overall game time.
