Why do we still have enmity?

[Reynhart]

(Also, in response to a prior poster claiming that damage is also binary, that is not the case. While the result is "Enemy is alive" or "Enemy is dead" and thus binary, dealing damage is not. The more damage you deal, the more damage you deal and the faster the enemy dies.
This scales infinitely, up until you have enough damage to kill the enemy in a single attack. With Enmity, it doesn't matter if you're 1 point above everyone else or 1,000,000 points above everyone else, the enemy will still be attacking you.
Thus once you generate enough enmity to maintain a lead over everyone else, more enmity generation is literally useless as it won't do a thing)

Probably being the prior poster you're talking about, I've presented a system where enmity would not just be "enemy is attacking you" and thus not binary anymore.

Enmity has simply never been an interesting or engaging mechanic. Even "Fun" tools to manipulate it (Such as Tricks of the Trade/Trick Attack) were simply just damage buffs that diverted enmity but where often redundant for their enmity generation outside of maybe making pulls easier.

Except that Trick Attack was better paired with Sneak Attack for another damage buff, that required hitting the back of the target. Problem is that pairing the two would result in massive damage and massive hate spike so that if the tank didn't know how to manage enmity (That would decay overtime), you'd take the risk of killing a DPS, or the stragery would be for the tank to purposefully lose aggro to the DPS for a short time so that the Thief could hit the back of the ennemy while being in the tank's back too...So your capacity as generating enmity would actually affect how your team would perform.
