When you get disconnected / reconnected to the internet you loose your instance / queue / spot in everything. This includes dungeon’s, wvwvw, etc.
I dc’d at the end of dungeon on the last boss, only to reconnect back in Lion’s Arch, and can’t get back to my friends without going through a zillion respawned mobs.. Or for WvWvW you queue for 60 minutes to get in, play for a bit and get DC’d back to Lions Arch..
Pretty poor effort / coding.
Why can’t ANet please save your spot in things for when you reconnect at least for 5 minutes. Surely it couldn’t be hard?
