2) The jump from 3/10 mythic to 4/10 mythic is huge. You actually need 20 good people, with gear, who know what they do and a bit of luck
3) People are burnt out. LEGION has been a long repetitive RNG grindfest.
4) People are fed up and quit. Mostly because of RNG. It simply isn't fun to see other people getting better gear although they are worse.
5) Content. Looks good on the surface, but is actually badly designed.
6) PvP is a complete failure. Some people like to do some PvP from time to time, atleast it was that way in older expansions. Doesn't happen with LEGION anymore, because PvP has been the worst it has even been, besides the changes who look good on paper, but in reality are the worst thing that ever happened to WoW PvP.
7) Class design is on an all time low. Some speccs have been pruned and simplified so much they are beyond help. Rotations and speccs just don't feel right. Reality and intuition are disconnect. (I haven't played ALL speccs so I can't speak for everyone)
And many more reasons, but to write everything down and go into the specifics would be too time consuming, but to sum it up : the problems are mostly due to design choices from Blizzard
