For the people who cant be arsed to read patch notes (ever, apparently):
There is no longer such a thing as "my Ashran" or "on my server".
Ashran is now REGION WIDE.
Every US/NA server is in one giant pool. When you ride in and queue, it throws you into whatever instance of Ashran has space.
It's that simple.
How to avoid this:
Hit the Premade Group Finder.
Find an event group that is nearly full/winning. PM the group leader and ask how things are going.
Join said group if things are going ok.
And here's the trick...
QUEUE... AFTER YOU JOIN THE GROUP.
It will queue you into THAT instance of Ashran.
You will win events.
Viola... its like magic.
What is happening when you ride, all unsuspecting, like a sheep, into Ashran without first joining a winning instance:
You're getting tossed into an instance where the OTHER faction has a winning PGF group going, and your side is cycling out quickly because of getting crushed.
Use the PGF
