So Ebonheart just has to eat their now gimped alliance. We all have to fight armies much higher in Valor rank and Zenimax will probably just let the problem handle itself while Ebonheart players just get face rolled by higher Valor, better geared players until people can finally catch up. We'll done Zos.
I have played a lot of MMO's in my day, seen a lot of bugs. Shoot done a lot of beta testing, and I do not think I have seen a bug like this before. Thousands and thousands of people are completely blocked from progressing their character. This is a type of bug you bring down a server if necessary to fix.
I am at a loss for words on how this being handled.
Sadly we cannot control the fix speed, or the pile of other players... though yesterday I did request a GM to come in to try and "herd the cats" to attempt this last night. Just managed to get a willing group on the DF side this morning (Thanking "The Sage" for getting them to listen and move). What we can do is report what we see as a possible working solution so people can try it or not. As many people are confirming the validity of moving away from the portal... maybe it will help the Dev team pinpoint the issue sooner.
I honestly do think everyone still stuck with the people refusing to move (since it is not very very probable it is keeping the portals from opening) should send help tickets in for GM intervention. If you could get a GM into the game in that area to force people to move... the portals will likely spawn, the people will be able to get ahead, all will be happy (ish).
P.S. - Avoid the ship graveyard quest later... still broken. Unless you feel like trying to find a workaround...
