As much as people complain about this poison, while it is still useful off weapon swap shivs/fan of knives about wow gold delivery, I just can not give up 7%-12% of my OVERALL damage for something that only helps me against a very small list of classes. In theory,  mind numbing offers good protection against things like abolish poison and poison cleansing totems. In practice, I find double wounds ability to instantly reapply the de buff far superior against those abilities, and offers far better pressure about wow gold delivery. You can easily get RNGed and not proccing wound poison for long stretches, especially if you are using 1.8 daggers. Double wound is just more reliable when it comes to the most important debuff, and the damage it does is deceivingly high to get more wow gold delivery.

One of very interesting choices Litreocola made in his spec is 2/2 Blood Splatter and Glyph of Rupture, he only has 1/3 improved eviscerate even with a RMP team where burst is supposed to be king! After trying it myself, I have to say I am very impressed by the amount of damage rupture does.

Almost that is 6000 damage off 25 second energy, goes right through armor. Eviscerate, as damaging as it can be, does very little against classes that eat us alive in arenas. Retribution paladins, warriors, death knights, heck even hunters have 38% damage reduction nowadays about wow gold delivery. Rupture + double wound with slice and dice is a lot of damage unmitigated by armor. Vs double plate teams; it really makes a huge difference. Against everyone else, I still rupture early and build up for a KS or eviscerate later to get more wow gold delivery. A burst window is usually 5 seconds, three ticks of rupture for 1500 damage, four wound procs, that is 3000 damage right through armor. The longer rupture duration really mess up other rogues too.
