It's what I'm trying,but I can only get one here and there. Everyone throws grenades and by the time I'm ready to throw I'm down. I kniw it isn't supposed to be easy,but I've done all the quests,and this is by far the most frustrating.

I've always mained goldy so i already completed it before aot. If you're struggling with it try them in pve for a while to get used to the way they travel etc
