You're asking for previously nerfed content, which is naturally "easier" due to being able to run it vastly overgeared/overlevel to be nerfed due to inability to handle the mechanics, yet you've been dealing with less punishing versions of them all through Heavensward. They just don't kill you or punish you as severely. However in Coil, which has already had many instant kill mechanics removed and the most punishing turns completely defanged, anything that was originally designed to kill you if you messed up will still do so. No amount of overgearing/being over level will ever make up for simply learning the mechanics. . . the same ones you've been (hopefully) doing in dungeons, against hunt mobs, in primal fights and even the 24 man raids now.
