Is the revolt time still 12 hours in a 2x speed game, or is it then 6hrs?
This only goes for worlds which have the 'conquest' mechanic instead of 'revolt'. Yes, for conquest worlds the conquest time is 24/world speed. Revolt always has a 12-hour 'lead up' period.this time change for conquest speed and go from 24hours for speed 1 till if i remember well 8hours for speed 3
When a world gets announced on the Fora, all settings will be made public before it opens. In these settings you can find world speed, unit speed, alliance cap, system used for conquering and wether it has morale/no morale. As shown in the image below, you can find the conquest-settings by going to the public fora and clicking on 'Worlds'-title (not Warrior, it shows a blank page)
You will be able to see the settings per server here, and will be able to see of any future servers when they open.
