This exploit of people queueing for a random dungeon and then teleporting to Fungal Grotto 1 has a negative trickle on effect for people who have queued for a specific dungeon to get gear.
Today my partner and I queued for Scalecaller Peak (on normal - come ON guys it's not even hard AND it's a daily today too) and 2 jerks who'd queued for a Random ported to FG1 even though I'd specifically said I needed Jorvuld's. They didn't care and went and completed FG1 and left the group so now I can't even queue for more people without having to start the dungeon all over again.
This is rubbish and shouldn't be allowed, the whole point of the dungeon finder is to get a group to complete content - ESPECIALLY ones you have specifically queued for.
