Maybe I'm misreading what you're attempting to express (which wouldn't be very surprising considering the horrible grammar) but LFR still isn't even slightly challenging. Tanks do not even follow the mechanics and still succeed (usually with 3 or more people afk as well) so most of your argument is already blown out of the water.
Pugs are also no different than Cata and still are as abundant as ever so unless you're not skilled enough to find anyway (understandable if you find LFR challenging) than you should have no trouble finding one.
Considering this posters past threads, his insulting demeanor, lack of responses and his extremely poor grammar I think it's pretty clear what the purpose of this thread is.
