LFR is not supposed to be main end game content, it's basically just story mode so people can experience the content without missing out on it. But something I've noticed here is that LFR is taking significantly long time. I am talking over five hours to do LFR at all for any of them. Agonizing.
So here's my idea. Tenacity buff that allows less people to do LFR content. The less people you have, the more buffed your stats are. Just like old school winter grasp. This would allow less people to get into the raid and continue doing it When people leave out of frustration. Again, keep in mind, LFR is not supposed to be endgame competitive content.
