The stats looks fine for me. When I play chanter the first time and when I was around level 4, I have the same feeling. But as the game goes my chanter gets better and better, especially after level 9.
Chanter is actually a class kind of underwhelming in lower difficulty as the combat ends too fast for chanter to shine. However it becomes one of the best class in POTD with prolonged combat.
Also early game chanter does have health issue as the main tank. It will be better if you have another tank to reduce the pressure.
As for Phrases, summons are good in general early to mid game until level 9 you will get two powerful phrases.
