I like the scholar (favorit healer, if i play a healer).
Fairy is cute. And, i like it more to raise a barrier who takes the dmg. As, to rely on the survival of the others and than heal the dmg.

And, i dont want a split between summoner and scholar. Its allowing me to lvl the summoner up at the same time, im lvling the scholar up (reason, why i have only little experience with the summoner, he is allways pulled with the scholar^^).

But to the skills can i understand OP a bit. I have trouble to see, when i should use the Seraphim or now the dress skill. Or the fairy HoT skill. It allways feels, as if the standard healing skills are enough for the fights.
