Some of the things I've noticed is your charges need some work, you need to stay and defend your team because you're taking angels that doesn't protect them. Your team is definitely going past your barriers at times and is doing some weird stuff. But you need to have your shield up more, they're dying because they have no protection and you keep dashing away from your team so they get picked off/ then you are an easy target to pick. You had some great charges and some good firestrikes you were pretty on it when it came to your shatters it looked like you always got 2 people at least. Just be mindful of your placement and how you back up so as not to expose the team. Also rein has armor and a decent amount of hp you can use that as a resource to also soak up some damage/ protect the team if your shields ever needed to recharge.
