Not saying it is difficult at all but the LFR queue is too susceptible to random class set-ups and should be tuned around accessibility. If you want the difficult version then the Extreme is there to go have fun in. I have never seen these things ever time out except for this one or whenever people talk about Shinryu on release.

It is not majorly over tuned but feels like about 3% and the button mash part is just cancer.
