I highly doubt they’ll fix it because they are 100% right, with enough SL gear you will be able to solo it…maybe…barely. So they are going to sit on their hands until 9.3 comes and if they are right then everyone will shutup 
If they are wrong then this will of course get worse. The problem is, come 10.0 launch (the xpac not prepatch) the same exact threads are going to popup but this time it’ll be BFA content because if we can’t do Legion now and they change nothing then we won’t be able to do BFA at 60/70 (whatever level next xpacs cap is).
