Keep Rend active, but don't over use it. try to use Rend as little as possible, but without ever allowing to be expire off the boss. Easier said than done, it takes practice. The rest, you will figure out. Just keep a tight rotation, do not slack on dps. Always push your rotation hard and fire off as many attacks as your rage allows for, as quickly as it allows for.
That's my advice...
Hey I am a Fury Raider,, I like your Arms build and plan to try it. I have never been arms so I have no idea on rotations. Can you help me with this and give me some pointers.
Thanks for any info.
