iso will never be a top meta duelist; he can't op like jett or yoru, if you need a duelist to get you out of jail free card theres reyna and jett, need a more support util duelist? theres reyna, yoru, neon. Iso can't dash as well, the only way to fix ISO is to bring back focus 2 shield orbs back, remove the ondemand shield, rework the wall where you can stop it like harbor's cascade(evaporates after like 3 seconds of stopping). rework his ult to where you have a stim beacon and the opponent doesn't.
