Alright so youāre talking about a difference of 1 damage over a 37 delay. The most noticeable difference of that will be fully hasted. Letās assume you always have a bard so youāre at something like 125% haste which puts you at a delay of like 17. Maybe 16, so weāll use 16 just for illustration.
1 over 16 delay is a ratio increase of .063 so youāre trading that ratio for 3000 damage.
Now, you got all kinds of damage bonuses, crits, heroic stats that change both that and the proc damage. But letās assume you proc at a rate of 1 proc per minute which is probably way low (base is like 2). So weāre probably overestimating your weapon damage and underestimating your proc damage. I didnāt look up resist rates for that proc so Iām just going to use one quarter of the damage (resist completely three out of four times on average). Which means Iām probably way underestimating your proc damage. Weāll call it 750 damage per minute.
Iām also not counting double attacks, ripostes, etc which would increase the value of your weapon damage and Iām assuming itās all going to wash out since weāre doing fuzzy math anyway.
That said, the raw additional damage is 1 every 1.6 seconds. That means over the course of a minute youāre doing a raw damage increase of at least ~38 damage. versus 750 from the proc. There would have to be a LOT of additional bonuses or a LOT of resists on the proc to close that gap to where the 1 damage is better than the proc.
Again, napkin math, so I could be wrong. But this is why Iād probably pick the proc aug.
