This is actually kinda accurate <_<; http://i.imgur.com/CKPkwmk.png

On a serious note. Are you playing on PS4 or PC? If you're using a controller, I highly recommend using the extended crossbars to manage all your skills. In addition to that, set it so you only rotate between two hotbars and make one for your tank stance, and the other for your DPS stance.

If you're MTing, you want to establish hate first and then work on keeping maim up. For multiple adds, I generally use 2 overpowers to start and then steel cyclone (when available) to keep up with aggro generation. Make sure to keep an eye on the aggro bars on the side to see if anyone is close to stealing hate and adjust accordingly. Make sure to use cooldowns on big hits and if you're tanking multiple adds to ease the healer's job. One thing to note is that inner beast heals you and gives you a short damage reduction buff, so use that as if it was a defensive cooldown.
