It was just announced that ESO is doing a Cyrodiil Population Cap Testing "Event" from 6. to 12. December 2023.
According to Brian Wheeler (Lead Combat Designer):
Heyo all!
Over the course of the next few days, we will be running some tests in Cyrodiil where we’ll be periodically adjusting the population caps. The first realm being tested is PC EU on Wednesday, December 6. During this time, we will increase population caps and monitor throughout the day through prime-time hours; if all goes well, we will do the same on PC NA and consoles later in the week.
We encourage everyone willing to fight for their Alliance to hop into their respective Campaigns because throughout the testing period until December 12, everyone in Cyrodiil will earn Double AP!
Thanks in advance for joining this population test for Cyrodiil and enjoy the double AP while the test is active. See you on the field!
Don't miss out on the double AP during the short "Event".
