NQ Nyzul is insanely easy to complete nowadays. Even the sh*ttiest 3-man groups shouldn't have trouble completing at least 10 floors in a run (seriously, how did some of us sometimes have so much trouble in the past just doing 5 floors per run?), a good group can do 15 or even 20, and due to the fact that there's pretty much no statics that do it anymore, it actually isn't as hard as you might think to find those two people with shouts.
Bro you totally making stuff up. You can easily get stuck on lamp floor. Also I shout for hours and can't find ONE person who is on the same floor as me.
