Guild Wars 2

Simple ready check pops up kind of like an overflow queue if you don’t hit ready by the time the timer runs out you get kicked from the zone if it’s full.

1) Kicks AFK’s and gets in people who will actually be there
2) The ready check itself flags as a warning for the raid to get ready

In my experience, losses happen due to leaving the megalaser slightly early. If you have AFK’rs, you have less than necessary cooperation to begin with. Did you have 4 commanders working together to split the map zerg up into 4 squads? 2 offensive and 2 defensive. Each one assigned to either the laser or a battery to protect. Hope that helps.
