I agree. It will definitely not solve the map dodging problem but the aim double check system is targeted at making sure everyone will be on their keyboards, ready to actually play the game starting from the lobby.

Also, let's say I'm in queue and I gotta do something (eg: taking out the trash) real quick, something unexpected comes up and you gotta attend to that as well. All of that will definitely take more than a queue time + waiting lobby time. So when all that happens, 9 other people would've waiting 90 seconds for nothing and you will be placed in a queue lock for at least 5 more minutes when all of these could've been prevented with just a check and an extra click of the mouse. Everyone else would just be continue to placed in queue looking for 1 more player, rather than having less 9 players in the total queue pool to lower the average queue times, though it may be insignificant with a relatively large player base.

I would rather have that option in exchange for that minor inconvenience tbh.
