Those zone clear NMs are like level 85 or something. You can kill those in Sparks gear without breaking a sweat. The only danger from any of them is Death, but it has a decently long casting time and you can stun it if you sub Dancer and aren't like "herp derp I go auto attack then go make a cup of coffee and come back as winnar k?" And even if you had Trusts, they despawn as soon as you die so they wouldn't help you solo anything if you can't deal with Death.
