Actually the LFG system for fractals, raids and strikes, is quite bad, specially because a lot of people prefer just to stay doing nothing for hours for their insane requirements of kps, ufs, li, etc. Than spend that time trying to do the content with people that probably don't have that quantity of requirements, but that they have done the content a lot. The system has to be improved to make it more automatic, and dont even have to worry about create it from scratch. They can just go to wow and see what they did and do something similar.
But really is insane that for example in my case, I didn't know about kps before and I throw away all decoration, and now is really difficult to me do content even knowing the raid mechanics, and having practically 2 legendary raid sets.
