Purifier newbie help to ultimate

This is what i am leveling like at the moment and i do feel some what squishy, And i presumed that the inquisitor seal was the reason to stand still since its kinda pointless if i move around and away from it.

I am unsure of mostly everything since i am new to the game.
Maybe gear problems or devotion or skills.
Would love to have some input.
