This is to explain the importance of Zone Commemoration. I promise you will not be sorry. I will be adding more info soon.
You can see, in the photos below, the huge difference in scores gained for coz depending on the completed percentage of Zone Commemoration. Both accounts trained roughly the same amount of troops yet one is at 5 boxes the other at 7.
Zone Commemoration is quite literally the most important thing in the game. I know it is difficult to complete. But that is why proper planning is so important. You have to determine which are the easiest 9 boxes to get and focus on completing those. Do not spread yourself too thin between all the days. Be realistic. The 9th box gets you 1500 courage medals. It is a trek to get to the 9th box. Use the hourly challenges as a way to maximize prizes and always use Coz Score increase tickets during the hourly that correlates to that coz day. There are usually at least 2 correlating hourlies in a row. If you pop your Coz ticket at the end of the hour it will carry over to the next hours challenge. This will maximize your coz scoring points while getting as many hourly challenges done as possible.
Once you can get a rhythm for how to get the most hourly challenges in each day and when the best ones are you will also increase the amount of speed ups making it easier to complete the coz boxes for the day.
Each day has it’s golden hours you can see below a shot of the guide I shared. It will show the active hour by highlighting it. Any hour that has bold green text is an hour with a correlating challenge to the coz day.
You can see below that each day is different. Build day has many challenges that match up to the hourlies. Where as troop day and tech day are more spread out and you have to watch them more closely.
