QP matchmaking changes

Can we have an option to NOT BE ABLE to queue in an ongoing match. I REALLY REALLY WILL NOT/DONT WANT to play a match 1min to be over. OR let me leave this match without ANY penalties… I mean. I will not play it anyways, you can let people choose if they are willing to play or not.

Also I only play Attack, I dont like defense or maps like Coloseo and Ilios. why isn’t an option to just search attack maps? I’m fine waiting 5min on queue, but I have to leave match before starting always to get a map I enjoy playing
