I hate havoc... like many other people i thinks its the worst part about Battle dawn! So I was wondering weather there was a way to tell when havoc was going to end so i can log in for the start of the new era and have nothing to do with havoc?! I have asked my admin several times but i have never got an answer back!
Is it random? Whenever the admin feels like starting a new era? a set 100 ticks?!

If you don't like havoc then don't play havoc. Just check frequently to see if the era restarts

What is the purpose of Havoc? I assume it does not effect the 'regular' era score so is it just a 'free for all' or 'mad minute' of death, mayhem and destruction?

i dont like playing in havoc as well, but some people do, so the best solution for us is not to log during havoc.. simple as that!

Havoc is pretty much a BD era on the brink of ending....Honestly I dont have a problem with havoc, to me its kinda fun
But if you dont want to play havoc, you can always just not log into the world until the reset.
