As a former SCH that is now playing AST I can only completely agree with the OP. The class is awesome to play, I love the randomness of the cards, the two stances of healing is interesting. Everything is fun while you are playing a normal dungeon or a Hard or Normal trial. However, when I went back to some EX Primals and tried solo healing some of them as I did with my SCH things started to show their true colors.
