Honestly never have this problem. I wait outside spawn calling to group up and run in circles while I wait and I only wait if I know more than one person died around the same time or if we're getting beat down and tactically need to group up. And actually tell them in voice chat what you're doing
The only time i throw is after 1 person gets picked 2 times as Im asking everyone to group up. Shits annoying, going into a 5v6 just for that guy to die again before eberyone spawns
