Questions & Channel Changing
I’m guessing there are as many instances of EotM as needed depending on how many players are playing it at the time. When an instance gets full, another one is made. You can leave EotM and then re-enter and hope you end up on a different map. The longer you are out of EotM the better odds you’d probably end up on a different instance.
I personally barely consider EotM to be WvW at all. I refer to the Borderlands and Eternal Battlegrounds as true WvW. EotM is just karma training. Very very few there take it seriously or put any effort into it.
You are always the same color that your server is that week. If you are green, you will always end up on the green side in EotM.
What decides the color of my server? A while back I was red.
The color of your server has a random element to it. If your server has the highest rating in your matchup (not current week’s score but overall WvW rating) then there is a good chance you’ll be Green. If you’re the second best, there’s a good chance you’ll be Blue. Finally if you’re the 3rd best, you’ll probably be Red. However, there is some randomness thrown in so that you’re not always the same color. The highest rated server in that matchup will usually be Green, but sometimes not.
