The fun thing about raven is that these skills of QWER can be linked together at will, so you can think of it as Taiji Biography in Dragon Slayer and the legendary swordsman's Nine Swords Alone. You should forget all the moves, and don't care about things that don't even move. You can use them wherever you want to go. Anyway, you can save three passive+attacks, about 6 seconds. Just cut it and buff will refresh for 6 seconds. There is no need to insert a skill interval for each A. It depends, the blood volume of you and your partner.
In fact, EQWQQ is the best choice if you have to break into the crowd in the later team battle. Give an extra A and you can die directly in the crowd. QAQA is only suitable for one-on-one hit or 1V2.
