I’ve seen a lot of disagreement on the Lady Deathwhisper fight over if it’s better for Hunters to use Viper Sting or Serpent Sting. I take the less intuitive path of Serpent Sting is better. This has been bugging me, and as we all know, I like being right, and I like maximal dps (as opposed to Predacon dps?) – so, I sat down and ran some tests.
First, no offense to anyone in the Viper camp, but I think a lot of the love for Viper on Deathwhisper is being people don’t quite fully examine the tooltip.
Stings the target, draining 4% mana over 8 sec (up to a maximum of 8% of the caster’s maximum mana), and energizing the Hunter equal to 300% of the amount drained. Only one Sting per Hunter can be active on any one target.
I think most people look at the “4% mana” part and think, “awesome, with something like 10 million mana, that’s like 400,000 mana! That’s like a full minute of my dps in eight seconds! (Light knows I did at first!) What we miss is the second part of that: “up to a maximum of 8% of the caster’s maximum mana” (that’s you, the Hunter). Math, raid buffed, has slightly less than 16,200 mana. 8% of that is 1296… ow. Viper is 1% every two seconds for eight seconds, so each two second tick is 324 mana drained.
Plinking Serpent Sting on a target dummy with no buffs beyond Aspect of the Monkeyhawk shows that a normal tick of Serpent Sting does an average, for Math, of 494 damage. He still has his 2pT9, and about 60% (unbuffed) of those ticks of Serpent were crits, averaging 1139. Plus, being Survival (yes, there’s still some Survival hunters left), while Serpent Sting targets take 3% more damage from his other abilities, like Explosive Shot – extra dps that comes from using Serpent, lost during Viper.
While Viper Sting seems, on the surface, to be potentially good, simple math (hah) shows that for Math, going Viper is a dps loss.
This really isn’t a hard and fast rule, “never use viper on Lady Deathwhisper”, though. Really, I want to say it seems generally suboptimal, but you might be a special case – fortunately, it’s not hard to check, if you care about pulling out that last extra hundred-some-odd / hundreds-of dps on Phase 1 – calculate 1% of your mana, and see if it’s a bigger number than an average tick of your serpent sting.
Though there is a time to use Viper Sting on Lady Deathwhisper, and that’s when you run low on mana. Sure, it does less damage than normal, but getting 24% of your mana bar back in eight seconds on a 15 sec cooldown beats eight seconds in Viper by leaps and bounds, let alone the amount of time you’d need to spend in viper to get that much mana back.
I know I’m not some leading authority, but the theorycrafting here is easy enough to try this at home and see – just, don’t blame me if somehow something goes horribly wrong. I’m not responsible for horrible mutants, wipeitis, wandering dps syndrome, or any other fallout you might randomly find. The world is a buggy place!
Fair winds and good hunts. Stay owning, my friends.
