Not only that, and even if you just pull the smallest amount of Monsters, which is usually just a Group of 2-3, a Healer can technically disable one single target for up to 52 seconds with sleep before it becomes immune to it, provided noone slaps it awake beforehand.

During Matoyas Relict, i noticed that the single target tankbusters from any Boss there do arround 95-100% of a synced down DPS maximum HP, and since it is always followed with a small breakphase of a boss that lasts a few seconds, it is enough of a time window to actually make any DPS Job a tank, as long as you provide them with a shield before it happens and heal them up afterwards.
