It has to do with doing DLCs with randoms yes, but all in one day I've queued for a random vet dungeon and it's been one of the new dlc dungeons every time. The worst part is it has been a group stuck each time waiting for a CP 780 to come and save them. I'm CP 710 at the moment, have a VMA desert and do pretty good DPS but I don't even get a chance to go to where the group is because I get kicked right after they see I'm not max level.
It's such a waste of my time, I'd rather avoid this problem altogether than just keep queuing, until I finally get a chance to actually play the game.
