<Masters of Death> - A thought experiment

[Rygar]

Imagine a world where all content is trivialized with standard min-max meta. You long for something fun, challenging... Out of the ashes emerges <Masters of Death>. The guild's only requirement? The ability to Feign Death!

Unless I'm wrong, this would be:
Shadowknight
Necromancer
Monk
Shaman (maybe... if sky ring obtained)(anything else?)

Could any meaningful content be achieved by these takers of the eternal breath? I'm curious.

-Can Trucidation be useful for a necromancer against raid mobs along with other taps?-If melee DPS simply FD when low HP, can rest of dps 'battle bind wound' to restore HP along with necro patch heals?-Is there a way to cheese rotating riposte disciplines against raid mobs when everyone can FD?-is an HT zerg even a thing with how often it is resisted?

Just a fun inquiry, nothing i'm taking seriously. Just bored and the thought crossed my mind. Curious if people see particular strats with this that can be useful even though we know something like this will never happen.
