Hi. Had longer post... then just made this tldr version and cut out most of post.

How much of an enmity impact do enmity altering traits and materia stack?

Has there been enough impact, where you as a tank does not need to use Accomplice on a DPS/healer to maintain enmity? Or as a DPS/healer, not needing to use Chameleon, Soughspeak, Quelling Strike, Collusion, etc to avoid enmity?

Has the Intimidation and Out of Sight traits been enough for parties generally?

I took a look at the Dated Maddening Dagger and if I recall, it had +25 enmity. How much enmity could be stacked on a belt in addition to this before reaching the item contribution cap?
