D/P or S/P Skill Rotation?
I can’t speak about S/P (I just can’t use sword… Having the majority of it’s damage tied to auto-attack bores me)
But for D/P:
Highest DPS rotation would be Shadow Shot spam (Deals about half the damage of Backstab but costs less than half the initiative as BP > HS) until 50% health and then Heartseeker spam is higher (Similar damage kitten at 25-50% health but costs less initiative)
Unless traited for 2 init back on stealth in which BP > HS > BS becomes best DPS until 50% (Then HS spam becomes best due to initiative costs)
Though usually “rotations” are based upon what is needed the most at the time. Burst warrants use of BP > HS > BS. Survivability warrants use of BP > Autos > BP. Gap closing warrants HS/SS usage.
With the way that initiative works you have to be flexible in your skill usage to maintain a nice flow of attacks to fit the situation as it changes.
