Disconnecting in Fractals.
They are supposedly working on a fix that will hopefully be out by the end of the month.
Fingers crossed.
It has already been stated that a fix will come at the end of the month https://www.guildwars2.com/en/news/fractals-of-the-mists-dungeon-improvements/
It should have been in place when fractals launched. ANET knows that people disconnect. ANET knows that there is nothing that either ANET or the player can do about some of these disconnects. That’s why they implemented the ability for us to reconnect to dungeons.
