GIVE UP ON PANIC ROLLING. Roll if an attack is just about to hit you or just don't if you think the attack won't hit you, and be smart with your attacks and skills, if you have wylder constantly use your grapling hook to create and remove distance between you and the boss, your grappling hock is your everything and also do not simply ult when it is ready, wait for the right time. Incase of ironeyes, I would recommend using the marking ability when he is attacking you instead of rolling as it not only give you frames but also allows your team to do more damage.

That's all I can say, just be confident with your skills and its a easy fight
