Getting a group together is time-consuming enough, but if everyone assembles just in time for a WB to despawn, your entire group is going to have ten full minutes of their lives flushed down a toilet waiting for a boss to spawn. It's bad, and it needs to be fixed months ago.
"A probable impossibility is preferable to an improbable possibility." - Aristotle
