My favorite class is Astrologian, because I love buffing people with the cards. I would love to play a full support class with enhancement and enfeeblement spells, but I don't believe they'll add it to the game due to its current meta. I hope they consider it in the future, making it in a way that, even without DPSing or healing, the overall dps/healing output would be equivalent due to the enhancing and enfeebling spells.
I also like the concept of fast healing and the way I can adapt to content/groups by selecting two different healing styles.
