Rage of Halone

[Sapphidia]

For the sake of comparing enmity generation for RoH and SB, SB generates more enmity?

You can easily compare the relative threat generation of Savage Blade, Rage of Halone, a full combo and spamming, by using the Potency x Enmity generation calc. Savage blade has a x3 enmity modifier, Rage a x5. Both get this when spammed out of combo, but it's a multiplier over damage done.

Fast Blade is 150 Potency and its enmity is x 1 of that. Savage Blade is 100 potency out of combo, 200 potency in combo, and enmity is x 3 of that. Rage of Halone is 100 potency out of combo and 260 in combo, and enmity is x 5 of that.

Therefore, -relative- enmity values for the moves (not counting any modifiers from Shield Oath etc) are:

Fast Blade = 150
Savage Blade = 300 out of combo, 600 in combo
Rage of Halone = 500 out of combo, 1300 in combo

So you can see that doing a full Fast/Savage/Halone combo = 150+600+1300 potency threat = 2050 enmity over 3 global cooldowns. It also applies the -10% strength debuff which is huge (Rage doesnt do this when not comboed).
Spamming Rage of Halone three times in the same time period gives 1500 potency of enmity over 3 global cooldowns.

A single Rage of Halone is okay for grabbing a bit of snap aggro at the start of the fight (Rage of Halone out of combo is the single highest threat move a paladin has that only takes one GCD, slightly more than a Shield Lob) but you're simply doing it wrong if you just spam Rage of Halone. You're generating 33% more threat AND applying a debuff if you do the full Fast/Savage/Halone combo.

TLDR - spamming Halone is bad.
