Unlike other stats such as Attack Magic Potency that won't be able to give a static percentage increase due to dLVL effecting it (though it would be cool if a difference in levels didn't do that, like in XI), the Enmity bonus from gear doesn't change based on the level of the monster you're facing. Because of that it should be possible to show this information as a percentage on equipment instead of an arbitrary number. Thanks to Kaeko's and Hal Walker's testing on Enmity we have a fairly clear picture of how much extra Enmity gear bonuses provide and the result is 1 Enmity = 0.1% increase.

Reasons why it should be changed: 1) Like mentioned above Enmity bonuses from gear don't scale based on the level of the monster, so unlike other stats a percentage to display the increase or decrease is actually feasible.

2) It's a simple change to the UI that won't take much effort to do.

3) Makes it easier to understand. While yes it is easy to know that "Enmity +100" is better than "Enmity +3", the actual increase in your performance per point is impossible to discern. Thanks to the above player testing, we know how much each point Enmity from gear does. So ignoring the fact that if a player wanted to know just exactly what "Enmity +100" is doing for them they would need to consult outside player tests instead of having that information available to them inside of the game, how is having "Enmity +10%" able to provide more information to the player than "Enmity +100"?

Answer: Square-Enix told us how Enmity is calculated.
"Enmity is now a culmination of all actions taken in battle with one point of damage equalling one point of enmity."

Why the current method can cause unnesessary confusion: "Enmity +100" is ambiguous and can only cause more confusion compared to "Enmity +10%". Using the above quote from Square-Enix themselves, who's to stop someone from thinking "Enmity +100" means "If I attack for 100 damage with Enmity +100, that means it's like I'm attacking for 200 damage in terms of hate"? Nothing is going to stop that person from thinking that because "Enmity +100" is ambiguous and means nothing by itself. "Enmity +10%" actually means something because we know 1 damage = 1 Enmity. Having a percentage listed makes the above potential situation far less likely to happen. A player will know a 10% increase will make his 100 damage attack act as a 110 damage attack Enmity wise. There's no room for confusion now.

In conclusion: It's an extremely simple change I feel should be done in order to make stats more transparent, easier to understand and limit confusion about how Enmity functions. (It also helps truly expose how pathetic some of the Enmity values on some gear is :P I don't believe there should ever be an Enmity bonus on gear that results in less than 1% of an increase/decrease in Enmity gained, as that's already extremely tiny and impossible to notice by itself, but we'll see if the devs change that someday)


Not terribly important anecdotal evidence below~

#1: I had a friend complain about the Enmity he was getting as a BLM so I suggested to grab some "Nerve Drops" that give "Enmity -80". His response?
"Does that mean each nuke I do will count as 80 less damage done?"
Due to the nature of these forums I'm sure someone will try to peg him as an idiot for not having checked the unofficial player testing that was done, but he's not an idiot and if the description was "Enmity -8%" he would have understood what it did for him and his performance immediately.

#2: I had a Gladiator come into an Ifrit fight wearing a "Dated Maddening Dagger" which has "Enmity +25".

Had that player known "Enmity +25" meant "Enmity +2.5%" I think he might have used a higher damage weapon to inflict more damage to Ifrit AND gain more Enmity in the process.
