hmmm was just doing a little youtube- exorcist research and i have to say ... magical doesnt look really interesting / strong -.-
magical exorcist
physical exorcist
i think if id go for magical exorcist id go for the 5 main skills (white tiger summon, the big ball, the slow seal, the lightning seal anid the int/magic buff) and then mix in some physical skills (like star in the sky or the one where he spins the weapon around himself and throws it -> something to hold the mobs in place and dmg them
)
but until the the priest patch comes id go for physical skills and then (maybe) switch over to magical when there are some good skills
