Succubus - Soothing Kiss

[Malakar]

My point was that you can still adapt your playstyle to work with it by waiting for two torments. But as Bonemage suggested, perhaps your aggro problem is because you're fighting mobs of higher level. I typically have to wait a lot more for torments against higher level mobs. Also, you might want to try it out against different mobs, some have shadow resistance which will resist torment more.
