Leaving Dungeons at the Start

[Nekodar]

Since patch 2.28 it's happened to me like 5/10 when searching dungeons. Before it could happen but not that often. Like once a week perhaps. Not 5 times in 2 days.

I currently need to do AK for my relic and well find group, tank leaves, healer leaves and me and the other dps just stands there for 5 minutes before deciding to leave and requeue.

Why did ppl start this trend with the patch?

They didn't start with this patch. And they apparently feel like eating the penalty rather than do that dungeon.
