On the subject of openers that aren't starting with garrote, due to lack of haste or generally awkward timing, which would be better between:
Ambush > Hemo > Ambush
Hemo > Ambush > Ambush
The first opener allows your original Hemo DoT to be affected by Find Weakness, but the first Ambush doesn't benefit from Sanguinary Veins. The second opener allows both Ambushes to benefit from Sanguinary Veins, but the Hemo Dot is no longer affected by Find Weakness. I guess my question is, is the 100% armor reduction added to the DoT stronger than the 35% increased power of one Ambush? It feels as if the DoT would win out here, but any confirmation would be nice.
Something else to consider is that Hemo could be recast after the opener with Find Weakness up, but the loss value of clipping the DoT and replacing a Backstab with a Hemo just to supercharge the DoT would probably be counter intuitive. Any thoughts would be appreciated!
