In the weeks leading up to TTK, as I LFG'd every VoG and CE I ran, I kept the good raid teams on my friends list (and deleted the bad). I told every one of the good teams I'd be available to do anything to help anyone during launch week. Ended up giving me two solid teams that got through the raid with no issue. I'd highly suggest this any time a new raid is coming, greatly relieves the stress of PUGs.
