Königsberg I do like the idea of an opponents blessing. Though no idea why its giving me the same message at 2700 medal range. Should be lots of players ...
Lol ... easy for French nations with their bonus reduced training time. Right up their alley this event, the french bases I visited lasted night had this extra thingy ...
I did manage to complete it with a couple of hours to spare. Numerous traing tactics and even some spending of crowns to hurry things along. Plus a change in strategy ... at least it was achievable.
This event needs plenty of time to complete but not impossible. I got the 150 wins in about 12hrs with French civ using lots of TB but training only 135 shock infantry (for fastest max troop regen) and several tactic blessings for protection and sabotage. That said, it was such a boring grind.
My method is using mix army as normal with three planes, find not very tough opponents and only target is clear defence tower to get troops return, so normally I end each battle with one min left. In this way I achieved the requirement and not very boring, it is just tiring as I can not take a break, though my skill to use three -planes improve a lot :0
