Additionally, your second specc looks good. You can also try without Inspiration and go for Shadowfiend if you're having long games. I see that you're trying to keep a healthy amount of Mastery. From my personal experience, you need alot of Mastery to really notice a difference. You could better reforge it into Crit cuz there's not much else to choose from. Unless you wanna go for alot of Haste. But prepare to sacrifice Resilience for that.
