OP got a good point regarding establishing a grace period for dcs and a better queue implementation but he/she/Preferred pronoun expressed in a really bad way...Like we all are in this together getting in line no need to flame each other, we already have something to bother us all.
Hope we could get some info from the dev team regarding both connection grace period and queue line stability and ability to go back to the queue in a more better implemented way instead of getting error and having to open the game and enter you credentials all over again.
