yes, they do
its when you pop out the window and right click on the window and readycheck ison there. but you have to be leader. also i know they give us LFG but yet not a ready check, ITS NEEDED< we cant not be doing these ghetto ready checks anymore , what we do is ask everyone to mount up if they are ready, but even that is stressful, how hard is it to add "are you ready? <yes> <no>"
