Sorry but you're just looking to blame "boosted 90s" for bad groups. The real truth is, people wipe in LFR all the time. Wipes in ToT due to idiocy is nothing new and has been going on ever since ToT was introduced into the game. People who don't know how to play queueing up for LFR is also not a new thing. The odds of completing ToT are the same as they have always been.
Oh, and it only said this had 3 pages of posts so far, so I'm sure this has been overstated even more.
