I've took some time to figure out the schedule for the new portal incursions, it basically cycles on a 6 hour interval in which each zone will be active 3 times.
So I've been doing some experiments together with Ixillius these past two days trying to figure out why some players get separated from their bodies and turn into anomalies when they enter aClass I Magic Rift.
So with yesterday's patch we got another bird related glider skin (and there's a golden one on the horizon as well).. Suddenly it hit me why this is probably happening..
I've just finished the new solo instance of Arah's story mode on an alt account. Some things to note:
You can only complete Arah's story mode at the end of Victory or Deathonceper character. (If you want play through it a second time you'll need to use a different character or hitch a ride with another player)
