It kinda works, the way I see it is that when attacking the boss everyone generates aggro, that relic bonus passively generates aggro on the boss, but you will still need generate your own aggro by attacking and being in the boss' face in order to keep it if the rest of your team is mashing R1 on the boss. If I'm actively poking the boss I DO notice I'm holding aggro for longer with the relic, but that means you HAVE to be active and not be a passive shieldbot, otherwise boss will ignore you.

So yes, it works, it's just hard.
