Now once a battle for our division has been finished, often we have to wait for other divisions to finish. In extreme situations it can be up to 35 minutes of waiting. Wouldn't it be better if each division fought independently?
Example:
A new campaign starts and every division starts at the same time. D4 finishes first at T90 - it immediately enters the 5-minute break and the second round. In the mean time, other divisions finish their rounds in a similar way (as soon as they reach 1800 domination points), go on a 5-min break and proceed further.
This way no one has to wait more than 5 minutes for the next round to begin. Faster divisions also get an advantage of contributing more campaign points (up to ~30% in rare cases) as they can fight more rounds than slower divisions in the same campaign.
