Tip overview

Use you shield to absorb massive damage from moji, also moji's snack time can be blocked with it

You have much more mobility in your kit, which you can use to stay safe. Also pay attention to other enemies in the surrounding area. If you can eliminate them, you can gather up your teammates and make the rest history.

Never, NEVER ult first. Save it for when he innevitably grabs you and tosses you off the map. When he does, spam your ult button - it will stop your momentum the moment he lets go, and bring you back to safety.

Since people like to run Enforcer and spam Juggernaut, try and save your Setback for when he winds up his dash.

Don't just mindlessly CC him. Once it's over or he walks out of the area, he can just Juggernaut away. Wait until the animation starts and then CC him to shut it down completely.
