Q:
Is "against the corruption" buggy?
Yes you’re expected to walk there and yes it’s bugged.
Back in September they changed the order of the level 70 and 80 storylines for some still unknown reason. A lot of these changes made no sense at all and one of the especially nonsensical parts was that the Pact’s final push towards Arah happened before the missions to establish a foothold in Orr.
So to explain how you were able to get in (and to get around the fact that they were sending level 70 players to a level 80 map) they had you ‘airlifted’ in to Orr. Now the story is back in it’s original order you’re able to walk there, but it looks like the instructions haven’t been fixed.
You can use /bug to report it in-game and it should be fixed at some point soon. In the meantime just follow the green swirly icon.
