Your party NEEDS to attack the SAME MOB for this to work.
Group of 3-4 mobs
Mark one
Shield Lob
Gather
Flash>>>Fast Blade>>>Savage Thrust>>>Rage of Halone>>>Repeat

the enmity you gain isn't worth the MP...it's only an INITIAL mob gatherer at the start of battle...nothing else

Mob's of 1 (boss)
Shield Lob and Begin with Fast Blade>>>Savage>>>Rage of Halone>>>Flash for moments of no damage on you...Repeat x3 and following 3 rotations just leave Flash out (could work in Riot Blade for MP lost)
