Using ISO ult effectively

in the Iso 1v1 how do you peak the 2 walls? Do u run through? Do u sit in the middle? What's the most optimal?

shoot them

i found the best play is holding middle to hold left/right side and then if they don't peek into you and give u a free kill you can just swing with confidence knowing they are on the other side than u held

i havent played ISO so i don't know, but i've consistently won the 1v1 as the person who's been ulted by swinging left or right instantly and catching the enemy Iso off guard

idk but im boutta just sit in the middle the whole time cuz ik the iso is gonna move around
