My boss pull rotation using unchained:
Infuriate > Tomahawk > BB Rotation > SE Rotation > Heavy Swing > Unchained > Berserk > Internal Release > Continue BB rotation. This rotation will drop EVERYONE's hate bar and make sure it stays there. Opening with this rotation ensures that most dps don't pass the 33% mark on the hate bars, and will keep BRDs who don't use quelling strikes at bay.

For junk pulls(Speed runs)
Infuriate > Tomahawk > Flash > Flash > Heavy Swing > Maim > Bloodbath > Unchained > Berserk > Internal Release > Overpower x3 > Flash > Overpower x1-2. This rotation works wonders on trash pulls where the dps has relic+1 or allagan and can easily pull monsters from you if you dont spam overpower. It will ensure you maintain hate 99.9% of the time.
