Which character in Vindictus do you think is the best?

Choose either Karok, Evie, Fiona, or Lann. (By the way, make an explanation why you think that character is the best) :P I play on East coast and I have a lvl 32 Evie, 35 Fiona and a 14 Karok. My Evie's name is Truviet, add me :D (I usually go on my Evie alot)
