Question about positioning Shiva, on last phase, during staff weapon she will do that attack with the 9 circles, where the circles rotate clockwise or counter clockwise. Immidiatly after this she will swap to her bow weapon.

My question is that if you decide while tanking her to run around to avoid those circles shiva will always face the party when she swaps to her bow.

I was told however to not move at all during the circles attack and to just take the hit + vulnerability, because that way when she swaps to her bow, her back is already to the party, making it easier for them to avoid the bow shots. Is this normal? How do you guys position shiva?
