Hey guys, would appreciate feedback on my Chimaerus parse please. Is it because I didn't hold my CDs until the adds?

I am using the blizzard rotation helper (glowy blue outline on the buttons) is that holding me back?

On first glance, it looks like you press raging blow way to much instead of prioritizing bt

u pressed bloodbath 10 times in a 9 minute fight.... check wowhead for priorities and if the rotation helper says to press raging blow that much, then yes it will hold you back
