Sounds like you lack leadership Skills and the common sense that it takes to seek out experienced players to team with.
After awhile you only have yourselfe to blame.
If your comming to the forums to rant about failing Elite level STFs in a pug group then it makes it obvious who the real stupid person is.
I'll get you a mirror
Oh I'm sorry you must be under the impression I want to give that much effort. Most games have a gating system for the elite versions of instances ala WOW. If you want to wrangle the droolers feel free, I don't.
You can lead all you want to, but in a PUG, don't expect everyone to listen. Simple solution is not to Pug Elite Cure. It only takes one player to screw up that STF. You can Pug the other two Elite STF's if you have no other options available to you though.
