Overall I like the feel of this set and enjoy playing it. I have two minor quibbles:
1. Cloudburst's slow cast time and slow time to get to the target are a bit of a pain. Most of the time the target is dead before it lands. Maybe reduce the cast animation time slightly and get rid of the travel time to get to the target.
2 Storm Cell is ok, but is slow to follow so you end up recasting it again and again. If it followed you a bit more closely or worked like a pet it might be better.
That said I really enjoy the set...it's fun to play with and I found the AOE pretty devastating, though it takes a little while to "brew up", meaning that in larger teams it probably isn't great.
LOVE the look of Direct Strike 🙂
