They root you if they hit when you are stunned. If you are running retribution keep an eye on your stability to lower your chances of getting rooted. If not, then you must react fast to any cc by using a stunbreak. When you are on shiro, to play safe don’t drop your energy below 25% until your legend swap is ready. That way you will always have a stunbreak ready. Don’t forget, rev has a really high uptime on evades/blocks, if you die prematurely from a non-condi source, it means you misrotated. Takes a bit of time to get used to all the micromanaging.
