Wriothesley Combo

So finally I decided to read his kit completely. This is the combo that I think we should use on him :- Start with burst > E skill > keep using normal attacks > charge attack after getting A1 buff, refresh buffs after E skill duration ends.

Burst can be used at the beginning or end. Pros of using at the beginning :- you get more energy particles. Recommended to use at the beginning with weapons like solar pearl. Pros of using at the end of the combo :- You get more damage because of the A2 passive.

Is this rotation correct or his perfect rotation has already been analysed that I am unaware of?
