On single targets I start with a Goring Blade combo then if necessary for mitigation/enmity RoH combo otherwise I use a Royal Authority combo and Royal Authority follows after whichever. Repeat until dead. Spirits Within, Sheltron and CoS are all used as close to cooldown unless I need to uses them to deal with mechanics.

My multitarget is Flash x2 -> Goring Blade 1st target -> Flash x2 -> GB 2nd target Flash x2 -> GB 3rd target -> (GB 1st -> RA -> RA) until all targets are dead. oGcDs Sheltron and oGcDs are used on cooldown. This does a very good job of generating multitarget enmity and dealing damage while keeping targets Blind for as much as possible.
